The performance of the missing transverse energy (Etmiss) reconstructed with the ATLAS detector is assessed in proton-proton collisions at a centre-of-mass energy of 7 TeV.
We report on results in randomly-triggered events, soft proton proton collisions and collisions with jets at high transverse momentum where Etmiss is expected to be zero.
Particular attention is given to tails in the...

We consider the generalized gauge mediated supersymmetry breaking (GMSB) models with the messenger fields which do not form the complete multiplets of SU(5) GUT symmetry. Such a situation may happen in the anomalous U(1) GUT scenario because the mass spectrum of the superheavy particle does not respect SU(5) GUT symmetry, although the success of the gauge coupling unification can be explained....

Very light gravitino scenario m_{3/2} < 16 eV is very interesting, since there is no cosmological problem. In such a scenario, the stability of the vacuum is an
important issue. However, it was observed that the masses of gaugino are relatively small in the model which has perturbatively stable vacuum. We show that such a model can be completely excluded/discovered at
very early stage of...

We discuss prospects for SUSY searches with signatures involving two photons in the CMS experiment. We describe methodologies for such searches, as well as tests of data-driven background methods using early 7 TeV data samples. These methods are designed to establish the level of QCD background in the tail of the MET distribution.

Searches for events with photons and missing transverse are motivated by
a number of
models for new physics, in particular models of gauge-mediated
supersymmetry. We show first results of searches for supersymmetry
in events with photons and missing transverse energy, with the ATLAS
detector at the LHC. The performance of the ATLAS detector in
identifying photons in first collision...

In supersymmetric models that are embedded in grand unified theories, new sources of flavour violation may appear, beyond the hypothesis of minimal flavour violation where all flavour-changing interactions are related to the CKM-matrix. The corresponding new flavour mixing terms at the electroweak scale can induce interesting signatures at colliders. I will focus on non-minimal flavour...
