7) Energy frontier physics beyond the standard model
Talk
Naturalness arguments for weak-scale supersymmetry favour
supersymmetric partners of the third generation quarks with
masses not too far from those of their Standard Model counterparts.
Top or bottom squarks with masses less than a few hundred GeV can also
give rise to direct pair production rates at the LHC that can be observed
in the data sample recorded by the ATLAS detector. The...

7) Energy frontier physics beyond the standard model
Talk
In this talk, the latest results from CMS on searches for stop and sbottom squarks
are presented. Searches for direct squark production and indirect production
through gluino cascades in a variety of decay channels are reviewed. The results
are based on 20 fb-1 of data collected during the 8 TeV LHC run.

7) Energy frontier physics beyond the standard model
Talk
Despite the absence of experimental evidence, weak scale supersymmetry
remains one of the best motivated and studied Standard Model extensions.
This talk summarises recent ATLAS results on inclusive searches for
supersymmetric squarks and gluinos, including third generation squarks
produced in the decay of gluinos. The searches involved final states
containing jets, missing...

Talk
In this talk, the latest results from CMS on searches for supersymmetry produced
through electroweak production channels are presented using 20 fb-1 of data
from the 8 TeV LHC run. A variety of complementary final state signatures and
methods are used, such as searches with Higgs, W, and Z bosons in the final
state, to probe gaugino and slepton production.

7) Energy frontier physics beyond the standard model
Talk
Searches for events containing two Higgs bosons are presented using several decay
channels of the h(126) boson. The analyses use pp collision data recorded at
centre-of-mass energies of 7 and 8 TeV, corresponding to integrated luminosities
of 5 fb-1 and 20 fb-1, respectively. Extended Higgs sector scenarios predict the
resonant decay of new particles into a pair of h(126) bosons. These...

7) Energy frontier physics beyond the standard model
Talk
The discovery of a Higgs boson with a mass of about 125 GeV has
prompted the question of whether or not this particle is part of
a larger and more complex Higgs sector than that envisioned in the
Standard Model. In this talk, the current results from the ATLAS
experiment on Beyond-the-Standard Model (BSM) Higgs searches are
outlined. Searches for additional Higgs bosons are presented...

7) Energy frontier physics beyond the standard model
Talk
After a Higgs boson with a mass near 125 GeV has been discovered, it is still
unclear whether this is the Higgs boson predicted by the Standard Model (SM) or
part of a different, possibly extended Higgs sector. Various models with extended
Higgs sectors are being considered, such as the minimal and next-to-minimal
supersymmetric extensions (MSSM and NMSSM) of the SM. Recent results...

A search for Higgs boson invisible decay modes has been carried out in events where the Higgs boson is produced in association with a Z boson or through Vector Boson Fusion. In the associated production search, electron, muon, and b-quark pair decay modes of the Z boson are considered. The analyses are based on proton-proton collision data collected with the CMS detector at the LHC collider at...

7) Energy frontier physics beyond the standard model
Talk
The discovery of the Higgs boson opens many perspectives to explore
physics beyond the Standard Model. This talk describes constraints
of new physics in a number of models using the combined measurements
of the coupling strength of the 125 GeV Higgs particle using the entire
ATLAS run-I data. The various models presented include an additional
real electroweak singlet, two Higgs...

7) Energy frontier physics beyond the standard model
Talk
At the LHC, the production of heavy resonances decaying into a pair of particles
can be probed at unprecedented centre-of-mass energies. Two-particle resonances
are predicted in a variety of BSM models and can be searched for in a largely
model-independent fashion. Results from searches for resonances in final states
with leptons, jets and photons based on the full dataset of 20 fb-1 taken...

7) Energy frontier physics beyond the standard model
Talk
Events containing several leptons are useful probes of new phenomena
due to the low background from Standard Model processes. We look for
anomalous production of prompt like-sign leptons or events with three
or more leptons, as well as search for excited leptons, heavy leptons
and heavy neutrinos. The searches use the data recorded in 2012 at
sqrt(s)=8 TeV centre-of-mass energy by...

7) Energy frontier physics beyond the standard model
Talk
Various extensions of the Standard Model predict the existence
of new types of quarks. We report on several search channels such
as vector-like quarks decaying to a Higgs boson and a top quark or to
a W boson and a b quark. The talk presents results from searches for
new resonances decaying to a top-antitop pair and a top-antibottom
pair, including the use of boosted top quark...

This talk presents the latest ATLAS results in the context of electroweak production of SUSY particle, R-Parity violating SUSY scenarios, and scenarios with long-lived SUSY particles. The results presented use the full 20/fb of sqrt(s) = 8 TeV p-p collisions collected by the ATLAS experiment in 2012. The prompt searches consider final states including leptons, jets (including b-jets) and...

7) Energy frontier physics beyond the standard model
Talk
Searches at the LHC are complementary to direct detection experiments. Very
low masses and several DM properties can only be studied at the LHC. In this
very recent field at accelerators, several analyses were developed and performed
with 2012 data. Final states with Monojet, monophoton, and monolepton are
all considered, as well as dark matter particles that are produced in...

7) Energy frontier physics beyond the standard model
Talk
Different approaches to finding evidence for dark matter at the
LHC are presented. These include searches for events with large
missing transverse momentum and a single jet, photon or W/Z boson.
Searches for hidden sectors in events with long-lived particles
resulting in displaced hadronic vertices or lepton-jet signatures
are also reported. Finally, studies sensitive to the presence...

7) Energy frontier physics beyond the standard model
Talk
Although the LHC experiments have put strong limits on coloured supersymmetric states, it is still possible that electroweakly interacting supersymmetric particles have masses in the range 100-200 GeV. Even outside of supersymmetry, candidates for the particle of dark matter may have masses in this range unconstrained by LHC data. In e+e- annihilation, the low backgrounds, precise knowledge of...

The Compact Linear Collider (CLIC) is an attractive option for a future multi-TeV linear electron-positron collider. A staged construction in several centre-of-mass energy steps from a few hundred GeV up to 3 TeV is foreseen. At high energies, CLIC provides sensitivity to a wide range of phenomena beyond the Standard Model through direct observation of new particles and precision measurements....
