DESCRIPTION:Speakers: Mr. GERHARDUS\, Andreas (Bethe Center for Theoretica
l Physics)\nTwo-dimensional gauged linear sigma models with N=(2\,2) super
symmetry are a powerful tool for studying the worldsheet theories of type
II string compactifications. We construct a certain class of non-Abelian g
auged linear sigma models that exhibit an interesting phase structure emer
ging from non-Abelian strong coupling dynamics. The observed phase structu
re leads to a duality proposal amongst these models\, for which we provide
further evidence by matching the respective two sphere partition function
s. As some of the models at low energies flow to non-linear sigma models w
ith Calabi-Yau target spaces\, the duality proposal results in a correspon
dence of non-complete intersection Calabi-Yau varieties.\n\nhttps://indico

DESCRIPTION:Speakers: Mr. SCHIMANNEK\, Thorsten (University of Bonn)\nThe
topological string theory partition function captures non-trivial invarian
ts of Calabi-Yau threefolds. In general\, target space symmetries acting o
n the cohomology induce an automorphic structure on the free energies. For
non-compact geometries with spectral curve of genus one this allowed to r
e-express the physical constraints in terms of modular forms. The construc
tion\, however\, relied on a certain quasi modular object\, the second Eis
enstein series. We generalise this procedure to spectral curves of genus t
wo and show that the appropriate automorphic objects are Siegel modular fo
rms. In particular\, we propose an analogue for the second Eisenstein seri
es and a generalised Ramanujan identity both of which have not previously
been described in the mathematical literature.\nOn this class of geometrie
s we provide a straightforward recipe for solving the topological string.\

DESCRIPTION:Speakers: Mrs. COMAN-LOHI\, Ioana (DESY)\nNon-perturbative asp
ects of N=2 SUSY gauge theories of class S are encoded in the algebra of f
unctions on the moduli space M-flat of flat SL(N)-connections on Riemann s
urfaces. Expectation values of Wilson and 't Hooft line operators are rela
ted to holonomies of flat connections and\, in the low-energy effective th
eory\, to Fock-Goncharov coordinates on M-flat. \nWe determine the non-com
mutative algebra of UV line operators from the quantization of Fock-Goncha
rov Laurent polynomials and find that it coincides with the skein algebra
studied in the context of Chern-Simons theory. Another realization of the
skein algebra is generated by Verlinde network operators in Toda field the
ory. These results provide evidence for the generalization of the AGT corr
espondence to higher-rank class S theories.\n\nhttps://indico.desy.de/indi

. In case the nearest-neighbouring heights differ by one unit\, and the in
teractions occur between the four vertices around the faces of the lattice
\, these models have a rich underlying algebraic structure that renders th
em exactly solvable. We consider specific boundary conditions that preserv
e this solvability: domain-wall boundaries and one\nreflecting end.\n\nAft
er introducing these models we explain how the underlying algebraic\nstruc
ture -- the so-called dynamical reflection algebra -- can be used as a sou
rce of functional equations characterizing the partition function of that
model\, and what can be learned from this approach.\n\nhttps://indico.desy

supergravity coupled to chiral multiplets with vanishing scalar potential
have been denoted as no-scale. Of particular interest in the context of s

linear multiplets. We classify all shift-symmetric no-scale supergravities
in both formulations and verify that they match upon dualization. Additio

type IIB Green-Schwarz action expanded around the minimal-area surface. W
e normalize the vev of the Wilson loops with respect to the 1/2 BPS circul

work we consider a set of soft supersymmetry breaking terms within the NMS
SM which leads to a small hierarchy between the supersymmetry breaking sca

he soft term in the Higgs sector are non-vanishing at the GUT scale. This
pattern can be found in gaugino mediated models and in higher-dimensional
orbifold GUTs. \nWe also study the phenomenological implications of this s

DESCRIPTION:Speakers: Dr. YOKOZAKI\, Norimi (INFN\, Rome)\nWe propose a fo
cus point gauge mediation model based on the product group unification (PG
U)\, which solves the double-triplet splitting problem of the Higgs multip
lets. In the focus point gauge mediation\, the electroweak symmetry breaki
ng scale can be naturally explained even for multi-TeV stops. It is known
that the focus point behavior appears if a ratio of the number of SU(2) do
ublet messengers to that of SU(3) triplet messengers is close to 2.5. Impo
rtantly\, this ratio (effectively) appears in our scenario based on the PG
U\, if the messenger field is an adjoint representation of SU(5) gauge gro
up. Therefore\, our focus point scenario is very predictive. It is also po
inted out the gravitino can be dark matter without spoiling the success of
the thermal leptogenesis.\n\nhttps://indico.desy.de/indico/event/11875/se

nNatural (axionic) inflation provides a well-motivated and predictive sche

ial tensor modes and thus a high mass scale of the inflationary potential.
Naively this seems to be at odds with low (TeV) scale supersymmetry\, esp
ecially when embedded in string theory. I will outline in the talk that lo
w scale supersymmetry is compatible with natural (high scale) inflation in
a string inspired setup. The mechanism requires the presence of two axion

etermine the relation between the fundamental input parameters and the ele
ctroweak vacuum expectation value. Depending on the input parameters the m
odel exhibits three qualitatively different regimes\, two of which allow f
or a hierarchically small Higgs vacuum expectation value. In one case we o
btain standard electroweak symmetry breaking whereas in the other electrow

not acceptable in a model based on the QCD axion\, in non-QCD models this
