the parameter space of the two-Higgs-doublet model searching for points w
ith a strong phase transition. The results show that the model is a robust
candidate for explaining baryogenesis\, especially in the light of the re

the suppression of proton decay mediating and other operators\, in heterot

t forbids the undesired operators\, and thus may arise only after $Z^\\pri
me$ breaking. We will discuss the constraints on such a $Z^\\prime$ arisin
g in string derived models and focus on the constraints arising from gauge
coupling unification. In two contrasting cases we will show that the phen
omenological constraints at the electroweak scale necessitate that the $Z^
\\prime$ charges are embeddable in $E_6$. We will discuss how free fermion
ic models with the required properties may be constructed.\n\nhttps://indi

DESCRIPTION:Speakers: Alexandra Oliveira ()\nIf the electroweak symmetry b
reaking is originated from a strongly coupled sector\, as for instance in
composite Higgs models\, the Higgs boson couplings can deviate from their
Standard Model values. In such cases\, at suficiently high energies there
could occur an onset of multiple Higgs boson and longitudinally polarised
electroweak gauge boson (VL) production. We study the sensitivity to anoma
lous Higgs couplings in inelastic processes with 3 and 4 particles (either
Higgs bosons or VL's) in the final state. We show that\, due to the more
severe cancellations in the corresponding amplitudes as compared to the us
ual 2 to 2 processes\, large enhancements with respect to the Standard Mod
el can arise even for small modications of the Higgs couplings. In particu
lar\, we find that triple Higgs production provides the best multiparticle
channel to look for these deviations. We briefly explore the consequences
of multiparticle production at the LHC.\n\nhttps://indico.desy.de/event/7

GeV while the lighter one can have a mass in the vicinity of 98 GeV\, thu
s explaining an apparent LEP excess\, or be much lighter. The successive d
ecay of this scalar pair into two light pseudoscalars\, followed by lepton
ic pseudoscalar decays\, produces clean multi-lepton final states with sma
ll or no missing energy. We emphasize that a dedicated experimental search
for multi-lepton final states can be a useful probe for this scenario and
\, in general\, for the NMSSM Higgs sector.\n\nhttps://indico.desy.de/even

llows for enhancements in the diphoton decay rate of the lightest CP-even
Higgs. In this talk the Higgs phenomenology of this theory with a hypercha
rgeless triplet is analyzed. In particular\, for any value m_A > m_h there
is a parameter region where the CP-even Higgs sector appears at colliders
as the SM one\, except for loop-induced corrections. At small m_A\, moreo
ver\, there exists a second parameter region where the lightest CP-even Hi
ggs phenomenology is as in the Standard Model except for decays into botto
ms and taus. Improvements in the CP-odd and charged Higgs searches will be
worthwhile to discriminate this scenario from the Standard Model.\n\nhttp

a couplings\, it is a crucial new piece of information constraining UV com
pletions of the Standard Model. In particular\, supersymmetry broken at an
intermediate or high energy scale with low tan(beta) is consistent with p
resent data and has an independent theoretical appeal. We analyze the poss
ible string-theoretic motivations for tan(beta)~1 in Higgs sectors realize
d on either 6- or 7-branes. We identify specific geometries where a vanish
ing quartic coupling may arise naturally and specify the geometrical probl
ems which need to be solved to determine its precise value in the generic
case. Finally we consider models with negative quartic couplings at the SU

l loop corrections to the volume axion decay channel are Planck-suppressed
. Assuming the Giudice-Masiero coupling is fixed at the string scale by a
shift symmetry in the Higgs sector\, we get a prediction for the effective
number of neutrino species\, N_{eff}. The result is too large to be consi
stent with recent WMAP and Planck data\, so the minimal model is ruled out

choice of solution to the equations describing the quantum gravitational
effects. Whereas one of the two solutions describes a suppression of power

ion scenarios where the Higgs is part of a five-dimensional vector field.
We demonstrate how the relevant mixing terms can be generated by loop effe
cts\, and in particular how this is related to the breaking of gauge symme
try for gauge-Higgs unification models. We further constrain the radion ma
ss and mixing using the observed Higgs production and branching ratios. Fi

DESCRIPTION:Speakers: Michael Schmidt ()\nThe recent LHC discovery of a Hi
ggs-like resonance at 126 GeV suggests that the minimal supersymmetric sta
ndard model must be modified in order to preserve naturalness. A simple ex
tension is to include a singlet superfield and consider the scale-invarian
t NMSSM\, whose renormalizable superpotential contains no dimensionful par
ameters. This extension not only solves the \\mu-problem\, but can easily
accommodate a 126 GeV Higgs. I will present our recent study of naturalnes
s in the scale-invariant NMSSM taking into account the constraints from LH
C searches\, flavor physics and electroweak precision tests. We show that
TeV-scale stop masses are still allowed in much of the parameter space wit
h 5% tuning for a low messenger scale of 20 TeV\, split families (with thi
rd-generation sleptons decoupled) and Higgs-singlet coupling \\lambda of o
rder one. For larger values of the Higgs-singlet coupling\, which can reli
eve the tuning in the Higgs VEV\, an additional tuning in the Higgs mass l
imits increasing the (lightest) stop mass beyond 1.2 TeV\, the gluino mass
above 3 TeV\, and electroweak charginos and neutralinos beyond 400 GeV fo
r a combined tuning better than 5%. This implies that the natural region o
f parameter space for the scale-invariant NMSSM will be fully explored at
the 14 TeV LHC.\n\nhttps://indico.desy.de/event/7161/contributions/81551/

DESCRIPTION:Speakers: Akin Wingerter ()\nIn terms of physics results\, 201
2 has been an exciting year. In July 2012\, the ATLAS and CMS collaboratio
ns have discovered a new particle that is consistent with the Standard Mod
el Higgs boson. At the same time\, the LHC has pushed the lower limits for
supersymmetric particles to new heights\, and this has contributed to the
anxiety in the physics community that SUSY\, if realized in nature\, may
not be "natural" after all. Complementary to these "direct" searches for n
ew physics\, the LHCb experiment has presented in November 2012 the first
evidence for the rare decay B_s -> mu+ mu- which strongly constrains super
symmetric models with large tanbeta. However\, the new results have not be
en limited to collider searches. In early 2012\, the Daya Bay and Reno col
laborations have measured a "large" neutrino mixing angle theta13 of about
9 degrees\, thereby strongly disfavoring the tribimaximal mixing scenario
which has been a paradigm in neutrino physics for the last decade. Also\,
the Xenon100 experiment has started to probe regions of the SUSY paramete
r space which are "preferred" by many models. In my talk\, I will explore
the consequences of these experimental results on generic SO(10) models wi
th Yukawa unification in general\, and on the so-called Dermisek-Raby (DR)
model in particular. After motivating why we might expect a grand unified
gauge group at some larger energy scale\, I will introduce the DR-model a
nd discuss how well it fits current data in light of the recent experiment
al results. I will conclude with predictions of the DR model that are test
able at the LHC.\n\nhttps://indico.desy.de/event/7161/contributions/81552/

ffective operators describing a dynamical Higgs sector\, is generalized to
the case in which the Higgs-like particle is light. Gauge a nd gauge-Higg
s operators are considered up to mass dimension five. This analysis comple
tes the tool needed to explore at leading order the connection between lin
ear realizations of the electroweak symmetry breaking mechanism - whose ex
treme case is the Standard Model - and non-linear realizations with a ligh
t Higgs-like particle present. It may also provide a model-independent gui
deline to explore which exotic gauge-Higgs couplings may be expected\, and
their relative strength to Higgsless observable amplitudes. The analysis
is reduced by nature to the consideration of flavour -conserving operators
except for the standard Yukawa-type fermionic couplings\n\nhttps://indico

DESCRIPTION:Speakers: Cedric Delaunay ()\nNature seems to have chosen a li
ght scalar to unitarize WW scattering. Yet\, the Higgs discovery at the LH
C does not fully resolve the electroweak symmetry breaking puzzle and one
is left to find out what renders the light scalar naturally insensitive to
(unknown) very short distance dynamics. New Physics models where the Higg
s emerges as a Goldstone boson of some new strong dynamics at the TeV scal
e provide an appealing solution to this problem\, alternate to supersymmet
ry. In this framework\, the large top mass requires that the top quak (and
left-handed bottom) is a composite object. There are however no low-energ
y hint regarding whether the first and second quark generations (and right
-handed bottom) are also composite objects or remain elementary states up
to very high energies. We argue in this talk that radiative Higgs coupling
s are relatively sensitive probes to the degree of compositeness of the li
ght quark flavors. We further elaborate on how and to what extend Higgs ra
te measurements at the LHC can be used to infer the flavor structure of th
e strong dynamics.\n\nhttps://indico.desy.de/event/7161/contributions/8155

DESCRIPTION:Speakers: Lorenzo Calibbi ()\nWe discuss a minimal modificatio
n of Gauge Mediation in which the messenger sector couples directly to the
MSSM matter fields. These couplings are controlled by the same dynamics t
hat explain the flavor hierarchies\, and therefore are parametrically as s
mall as the Yukawas. This setup gives rise to an interesting SUSY spectrum
that is calculable in terms of a single new parameter. Due to large A-ter
ms\, the model can easily accommodate a 125 GeV Higgs with a relatively li
ght SUSY spectrum. The flavor structure depends on the particular underlyi
ng flavor model\, but flavor-violating effects arise dominantly in the up-
sector and are strongly suppressed in Delta C =2 observables. This structu
re allows to account for the recent observation of direct CP violation in
D-meson decays.\n\nhttps://indico.desy.de/event/7161/contributions/81558/

DESCRIPTION:Speakers: Kamila Kowalska ()\nThe discovery of the Higgs boson
at 126 GeV seems to imply masses in the multi-TeV regime for the simplest
constrained SUSY models. Thus\, with the exception of limited regions of
the parameter space where stop mixing is large\, in these scenarios the ne
w physics might be out of reach even for the 14 TeV run. We discuss the pr
ospects of using two alternative and complementary ways to explore the hig
h-mass regions of the parameter space of the CMSSM and the NUHM: 1) We qua
ntify the impact of reducing the experimental error in the measurement of
$BR(B_s\\to\\mu^+\\mu^-)$ to about 5$\\%$ around the Standard Model value.
We show that\, in the CMSSM\, $BR(B_s\\to\\mu^+\\mu^-)$ has power to disf
avor the A-funnel region that\, otherwise\, could neither be probed by dir
ect SUSY searches at the LHC nor by direct dark matter searches. We also d
iscuss the case of the NUHM\, where the constraining power of $BR(B_s\\to\
\mu^+\\mu^-)$ is not as significant. 2) We show that the multi-TeV region
of the parameter space of both models will be\, for the most part\, sensit
ive to direct dark matter searches in future one-tonne detectors. A nearly
complete experimental testing of the CMSSM over multi-TeV ranges of super
partner masses\, far beyond the reach of direct SUSY searches at the LHC\,
can therefore be achievable. For the NUHM\, it will be more difficult to
derive detailed information\, but light can be shed on the model in a few
cases.\n\nhttps://indico.desy.de/event/7161/contributions/81561/

DESCRIPTION:Speakers: Martin Spinrath ()\nWe revisit a two right-handed ne

with the recently proposed new type of constrained sequential dominance (
CSD2)\, involving vacuum alignments along the (0\,1\,-1)^T and (1\,0\,2)^T
directions in flavour space\, which are proportional to the neutrino Dira
c mass matrix columns. In this paper we construct a renormalizable and uni
fied indirect A4xSU(5) model along these lines and show that\, with sponta
neous CP violation and a suitable vacuum alignment of the phases\, the cha
rged lepton corrections lead to a reactor angle in good agreement with res
ults from Daya Bay and RENO. The model predicts a right-angled unitarity t
riangle in the quark sector and a Dirac CP violating oscillation phase in
the lepton sector of delta approximately 130 degrees\, while providing a g
ood fit to all quark and lepton masses and mixing angles.\n\nhttps://indic

DESCRIPTION:Speakers: Hyun Min Lee ()\nWe explore the interplay between li
nes in the gamma-ray spectrum and LHC searches involving missing energy an
d photons. As an example\, we consider a singlet Dirac fermion dark matter
with the mediator for Fermi gamma-ray line at 130 GeV. A new chiral or lo
cal U(1) symmetry makes weak-scale dark matter natural and provides the ax
ion or Z' gauge boson as the mediator connecting between dark matter and e
lectroweak gauge bosons. In these models\, the mediator particle can be pr
oduced in association with a monophoton at colliders and it produces large
missing energy through the decays into a DM pair or ZZ Z gamma with at le
ast one Z decaying into a neutrino pair. We adopt the monophoton searches
with large missing energy at the LHC and impose the bounds on the coupling
and mass of the mediator field in the models. We show that the parameter
space of the Z' mediation model is already strongly constrained by the LHC
8 TeV data\, whereas a certain region of the parameter space away from th
e resonance in axion-like mediator models are bounded. We foresee the mono
photon bounds on the Z' and axion mediation models at the LHC 14 TeV.\n\nh

omposite Higgs model with minimal tuning. The Higgs is a (pseudo-)Goldston
e boson from the spontaneous breaking of a global SO(5) symmetry to an SO(
4) subgroup. The peculiarity of our construction lies in the specific choi
ce of the SO(5) representations of the 5D fermions which reduces the tunin
g to the minimal model-independent value allowed by electroweak precision
tests. I analyse the main differences between our 5D construction and othe
r descriptions in terms of purely 4D field theories. 5D models show a gene
ric difficulty in accommodating a light Higgs without reintroducing large
corrections to the S parameter. I propose a specific construction in which
this tension can be relaxed. I discuss the spectrum of the top partners i
n the viable regions of parameter space and predict the existence of light
exotic quarks\, Υ\, of charge 8/3 whose striking decay channel Υ → W
+W +W +b can lead to either exclusion or confirmation of the model in the

DESCRIPTION:Speakers: Benoit Schmauch ()\nI present a model of baryogenesi
s through leptogenesis\, inspired from arXiv:0804.0801\, in which a lepton
asymmetry is generated by the CP-violating decay of an electroweak scalar
triplet. This triplet also gives rise to neutrino Majorana masses through
the type II seesaw mechanism. Therefore\, there is a very direct link bet
ween the CP asymmetry and neutrino parameters\, which are already known or
could be measured by future experiments. I study the impact of flavor eff
ects and compute the final baryon asymmetry predicted by the model. In par
ticular\, the final baryon asymmetry strongly depends on the mixing angle
theta_13. The value measured by the Daya Bay experiment is in the right ba
llpark to account for the observed baryon-to-photon ratio.\n\nhttps://indi

DESCRIPTION:Speakers: David Nolde ()\nWe discuss recent progress on supers
ymmetric tribrid inflation\, a variant of hybrid inflation which is partic
ularly suited for connecting inflation with particle physics. Inflation en
ds with a phase transition near the GUT scale\, and the inflaton can be a
D-flat combination of charged fields in the matter sector of the particle
theory. This relates the inflaton couplings -- which can be constrained by
measurements of the CMB -- to the properties of matter particles\, which
may be observable in the low-energy theory. In this talk\, we identify thr
ee different regimes of tribrid inflation and summarize their respective p
redictions for the CMB spectrum. Afterwards\, we explain how the framework
of tribrid inflation may be applied in model-building to realise tribrid
inflation in explicit SUSY particle physics models near the GUT scale.\n\n

DESCRIPTION:Speakers: Javier Rubio ()\nThe Higgs-Dilaton cosmological mode

d a dark energy dominated stage responsible for the present day accelerati
on. The common origin of both processes gives rise to a non-trivial relati
on between the spectral tilt of scalar perturbations and the dark energy e
quation of state. We study the self-consistency of this model from an effe
ctive field theory point of view. Taking into account the influence of the
dynamical background fields\, we determine the effective cut-off of the t
heory\, which turns out to be parametrically larger than all the relevant
energy scales from inflation to the present epoch. We finally formulate th
e set of assumptions needed to estimate the amplitude of the quantum corre
ctions in a systematic way and show that the connection between the early
and late universe observables remains unchanged if these conditions are sa

l consistent with the Standard Model within 1-2 sigma\, the excess could b
e also a first hint of physics beyond the Standard Model. We argue that th
is effect could be attributed to the production of scalar top quarks withi
n supersymmetric models. The stops of mass ~200 GeV has the right cross se
ction and under some assumptions can significantly contribute to the final
state of two leptons and missing energy. We scan this region of parameter
space to find particle masses preferred by the WW cross section measureme
nts. Taking one sample benchmark point we show that it can be consistent w
ith low energy observables and Higgs sector measurements and propose a met

ive axial-vector coupling of the gluon on spin polarization observables in
$t\\bar{t}$ pair production at the LHC (arXiv:1212.3272\, to appear on PR
D). Working at leading order in QCD\, we compute the $t\\bar{t}$ spin-corr
elation and left-right spin asymmetry coefficients in the helicity basis i
n the laboratory frame as functions of the new physics scale $\\Lambda$ as
sociated with this coupling. We found that the $t\\bar{t}$ invariant mass
dependent asymmetries are more sensitive to the scale $\\Lambda$ than the
corresponding inclusive ones\, in particular when suitable cuts selecting
high $t\\bar{t}$ invariant mass regions are imposed. In the context of thi
s scenario\, we show that the LHC has potential either to confirm or to ru
le out the Tevatron FB top asymmetry anomaly by analyzing the $t\\bar{t}$
spin-correlation and left-right polarization asymmetries. On the other han
d\, stringent lower bound on the new physics scale $\\Lambda$ can be set i
n this scenario if no significant deviations from the SM predictions for t
hose observables will be measured.\n\nhttps://indico.desy.de/event/7161/co

DESCRIPTION:Speakers: Giorgio Arcadi ()\nDecaying dark matter is an intere
sting and viable alternative to the common paradigm of stable dark matter.
Our purpose is to investigate whether the LHC can probe scenarios of deca
ying DM. Although the limits on the DM lifetime forbid the direct collider
observation of its decays\, the couplings responsible for these processes
can determine\, thanks to crossing symmetries\, DM production cross secti
on. In this case a collider analysis outcome can be combined with an event
ual dark matter indirect detection in order to get better insight of DM pr
operties. We thus propose a model independent study of operators connectin
g the dark matter particle with SM model quarks or\, possibly\, with gauge
bosons. Relevant indirect detection limits\, namely antiprotons and gamma
-rays\, already disfavor the simplest configurations of direct coupling of
the DM with Standard model states. More promising turn to be instead scen
arios in which the interactions of the dark matter are mediated by a scala
r state carrying color charge or at least electromagnetic. Its production
is not affected by ID limits while at the same time it induces three-body
decays of the dark matter. The same couplings also determine decays of the
scalar into DM and SM states which can be observed at the collider. In th
is framework several scenarios can be distinguished\, featuring WIMP DM as
well as FIMP and superWIMP configurations. For each scenario the relevant
constraints from dark matter observables have been investigated. In addit
ion have been identified the current and next future collider searches of
new Physics which are relevant for the particle physics framework under co
nsideration.\n\nhttps://indico.desy.de/event/7161/contributions/81595/

DESCRIPTION:Speakers: Masaki Asano ()\nAn analysis of the Fermi gamma ray
space telescope data has recently revealed a resolved gamma-ray feature cl
ose to the galactic center which is consistent with monochromatic photons
at an energy of about 130 GeV. If interpreted in terms of dark matter (DM)
annihilating into \\gamma \\gamma\, this would correspond to a DM particl
e mass of roughly 130 GeV. The rate for these loop-suppressed processes\,
however\, is larger than typically expected for thermally produced DM. Cor
respondingly\, one would generically expect even larger tree level product
ion rates of standard model fermions or gauge bosons. Here\, we quantify t
his expectation in a rather model-independent way by relating the tree lev
el and loop amplitudes with the help of the optical theorem. As an applica
tion\, we consider bounds from continuum gamma rays\, radio and antiproton
data on the tree level amplitudes and translate them into constraints on
the loop amplitudes. We find that\, independently of the DM production mec
hanism\, any DM model aiming at explaining the line signal in terms of cha
rged standard model particles running in the loop is in rather strong tens
ion with at least one of these constraints\, with the exception of loops d
ominated by top quarks. We stress that attempts to explain the 130 GeV fea
ture with internal bremsstrahlung do not suffer from such difficulties. (b

short lifetime of proton\, we have found that it is possible to evade the

articles have masses much heavier than the electroweak scale. Since the re
sultant proton lifetime lies in the regions which may be reached in the fu

DESCRIPTION:Speakers: Mikael Dhen ()\nThe talk will be based on the paper
arXiv:1209.2679\, in which is computed the μ → e conversion in the type
-I seesaw model\, as a function of the right-handed neutrino mixings and m
asses. The definite predictions will be presented and discussed. In partic
ular\, the ratios between the μ → e conversion rate for a given nucleus
and the rate of two other processes which also involve a μ − e flavor
transition: μ → eγ and μ → eee. Indeed\, for a quasi-degenerate mas
s spectrum of right-handed neutrino masses -which is the most natural scen
ario leading to observable rates- those ratios depend only on the seesaw m
ass scale\, offering a quite interesting testing ground. Furthermore\, it
turns out that planned μ → e conversion experiments would be sensitive
to masses as low as 2 MeV. Finally\, taking into account other experimenta
l constraints\, future μ → e conversion experiments will be fully relev
ant to detect or constrain sterile neutrino scenarios in the 2 GeV−1000
TeV mass range.\n\nhttps://indico.desy.de/event/7161/contributions/81619/

the correct lepton mixing pattern generated by some discrete flavor symmet
ry (barring large next-to-leading order corrections in concrete models). I
n this work we assume that neutrinos are Majorana particles and perform a
general scan of all finite discrete groups with order less than 1536 to ob
tain their predictions for lepton mixing angles. To our surprise\, the sca
n of over one million groups only yields 3 interesting groups that give le
pton mixing patterns which lie within 3-sigma of the current best global f
it values. A systematic way to categorize such groups and the implications
for flavor symmetry are discussed.\n\nhttps://indico.desy.de/event/7161/c

DESCRIPTION:Speakers: Andreas Goudelis ()\nThe recent LHC discovery of a H
iggs-like particle that could be involved in electroweak symmetry breaking
places strong bounds on the parameter space of supersymmetric models. In
particular\, it has been argued that minimal gauge mediated supersymmetry
breaking scenarios seem to be at odds with a Higgs boson of ~126 GeV. Supe
rsymmetric quiver gauge theories are an already well-established attractiv
e class of models\, communicating SUSY breaking to the visible sector via
linking fields. These models arise naturally in high-energy models\, and i
nterpolate between general gauge and gaugino mediated supersymmetry breaki
ng. Recently\, it has been shown that they can fairly easily accommodate a
Higgs boson of ~126 GeV. In this talk\, we will explore phenomenological
aspects of SUSY quiver models relevant both for colliders and dark matter
searches.\n\nhttps://indico.desy.de/event/7161/contributions/81624/

n which one Z_2 factor acts as a roto-translation. Since for this orbifold
the fixed tori are only identified in pairs but not orbifolded\, four-dim
ensional chirality can never be obtained using standard techniques alone.
This situation is typical for orbifolds that have vanishing Euler number.
However\, chirality is recovered when its tori become magnetized. To exemp
lify this\, we construct an SU(5) GUT on the Schoen manifold with Abelian
gauge fluxes\, which becomes an MSSM with three generations after an appro
priate Wilson line is associated to its freely acting involution.\n\nhttps

DESCRIPTION:Speakers: Nicki Bornhauser ()\nFinding signs of new physics an
d even knowing the underlying theory does not automatically come along wit
h the knowledge of the model parameters. In most new physics theories the
relation mapping the measured observables onto the model parameters is unk
nown. In this talk the ability of a neural network is demonstrated to find
this unknown relation in parameter space. As example different reference
regions of the mSUGRA parameter space are examined in the context of the L
HC with a center of mass energy of 14 TeV. But in general a neural network
can also be used for any other model. For a given measurement the artific
ial neural network directly computes the values of the model parameters an
d their errors.\n\nhttps://indico.desy.de/event/7161/contributions/81632/

DESCRIPTION:Speakers: Suchita Kulkarni ()\nIf supersymmetry is the solutio
n to the Higgs mass hierarchy problem\, this requires the existence of lig
ht stops and sbottoms. The current reach of the experimental searches for
stops and sbottoms at the LHC is however still limited. In this work\, we
exploit the information about top polarization in sbottom (and stop) decay
s into tops\, in order to gain better control over the signals arising fro
m these sparticles. We discuss various scenarios leading to distinct top p
olarization. Further\, we investigate different observables related to top
polarization and comment upon their helpfulness to improve searches for t
hird generation super-particles.\n\nhttps://indico.desy.de/event/7161/cont

DESCRIPTION:Speakers: Enrico Maria Sessolo ()\nThe discovery of the Higgs
boson at 126 GeV seems to imply masses in the multi-TeV regime for the sim
plest constrained SUSY models. Such a heavy supersymmetric spectrum is som
ewhat at odds with the naturalness criterion. Moreover\, in such a framewo
rk it is impossible to obtain the correct value of $(g-2)_\\mu$. By constr
uction\, SUSY models with light sleptons and light third generation squark
s do not present the same problem. In this context we analyze the status o
f a version of the MSSM with 9 free parameters at the end of LHC Phase 1 r
uns. We investigate the impact on the parameter space of different direct
SUSY searches using a statistical approach. We also include various other
constraints from b-physics\, the anomalous magnetic moment of the muon\, t
he relic density and direct and indirect detection of dark matter. All exp
erimental results are implemented through the likelihood functions\, inclu
ding the limits from XENON100 and from two 8 TeV CMS searches (inclusive s
earch of SUSY particles with $\\alpha_T$ and electroweak production)\, for
which the likelihood is constructed through simulation of the signal yiel
ds to be compared with observed events and backgrounds given by the experi
mental collaborations.\n\nhttps://indico.desy.de/event/7161/contributions/

SUMMARY:A Zip-Code for Quarks Leptons and Higgs Bosons

DESCRIPTION:Speakers: Paul Oehlmann ()\nThe location of matter fields and
the pattern of gauge symmetry in extra dimensions are crucial ingredients
for string model building. We analyze realistic MSSM models from the heter
otic Z6 Mini-Landscape and extract those properties that are vital for the
ir success. We find that Higgs bosons and the top quark are not localized
in extra dimensions and live in the full D=10 dimensional space-time. The
first two families of quarks and leptons\, however\, live at specific fixe
d points in extra dimensional space and exhibit a (discrete) family symmet
ry. Within a newly constructed Z2XZ4 orbifold framework we further elabora
te on these location properties and the appearance of discrete symmetries.
A similar geometrical picture emerges. This particular Zip-code for quark
s\, leptons and Higgs bosons seems to be of more general validity and thus
a useful guideline for realistic model building in string theory.\n\nhttp

DESCRIPTION:Speakers: Pramod Shukla ()\nIn the context of type IIB orienti
fold compactifications\, we present a new class of Kaehler moduli inflatio
n realized in the LARGE volume scenarios. The inflaton is a Kaehler modulu
s corresponding to the volume of a so-called "Wilson" divisor which is rel
evant for supporting the poly-instanton corrections. Further\, this standa
rd single-field model is generalized into a two-field model by the inclusi
on of respective axion modulus\, and large non-Gaussianity signatures are
observed in beyond slow-roll regime. Note: The talk would be based on the
papers arXiv:1205.2485 (JHEP 1206 (2012) 162)\, arXiv:1208.1160 (JHEP 1211
(2012) 101) and arXiv:1301.6076 (JHEP 1303 (2013) 061).\n\nhttps://indico
