Warped Extra Dimensions provide an elegant solution to both the gauge hierarchy problem and the flavor puzzle of the Standard Model of Particle Physics. The hierarchies between the electroweak and the Planck scale as well as those within the flavor sector are addressed in a five-dimensional setup with non-factorizable geometry.
As the Higgs boson has to reside close to the TeV boundary, it...

First results of the SUSY search in the 1-lepton+jets+ETMiss channel with the ATLAS experiment were made public recently. A precise understanding of the Standard Model backgrounds was crucial for these results. This talk will give a short overview about the Standard Model background estimation techniques and results.

In simple SO(10) SUSY GUT the top, bottom and tau Yukawa couplings unify at the GUT scale. It is well known that Yukawa unification (YU) consistent with radiative electroweak symmetry breaking requires non-universal scalar masses at the GUT scale. YU prefers also the negative sign of parameter \mu. However, negative \mu is typically disfavoured by the measurements of the muon anomalous...

A measurement of the production cross-section for top quark pairs in pp collisions at sqrt{s} = 7 TeV is presented using data recorded with the ATLAS detector. Events are selected in the lepton+jets topology by requiring a single lepton (electron or muon), large missing transverse energy and at least three jets. No explicit identification of secondary vertices inside jets (b-tagging) is...

In 5D SUSY GUTs, wave-function localization permits to reproduce flavour hierarchy. As this mechanism also acts on SUSY breaking parameters, it can potentially solve the SUSY flavour problem.
Here we carry out a quantitative analysis of the case of Holographic Grand Unification, which is a warped SU(6) GUT with pNGB Higgses on the IR brane. To break SUSY, we use independently
radion...

The LHCb experiment is designed to perform flavour physics measurements at the Large Hadron Collider. Using data collected during the 2010 run, we reconstructed a sample of Hb --> h+h'- decays, where Hb can be either a B0 meson, a Bs0 meson or a Lambda_b baryon, while h and h′ stand for pi, K or p. Such decays are sensitive probes of the Cabibbo-Kobayashi-Maskawa matrix and have the potential...
