Recent results on Higgs searches at the LHC by the ATLAS and CMS collaborations claim the observation of a new boson with properties compatible with the Standard Model (SM) Higgs boson, at a mass of about 126 GeV. The production rate of the new particle seems compatible with the SM prediction. In some models beyond the SM, an Abelian Hidden sector is coupled to the Standard Model, and the...

We review the Universal Extra-Dimensional Model compactified on a $S^1/Z_2$ orbifold, and the renormalisation group evolution of quark and lepton masses, mixing angles and phases both in the UED extension of the Standard Model and of the Minimal Supersymmetric Standard Model. We consider two typical scenarios: all matter fields propagating in the bulk, and matter fields constrained to the...

The electromagnetic calorimeter of CMS (ECAL) is a hermetic, fine grained and homogeneous calorimeter containing 75848 lead-tungstate (PbWO4) crystals, completed by a silicon preshower installed in front of the endcaps. The ECAL sensitivity to decay modes with electromagnetic objects in the final state, such as narrow resonances decaying into two photons, is achieved through i ts excellent...

I will argue that in heavy-ion collisions the observed strong quenching of heavy quark flavors at intermediate momenta has a sizable contribution from binary scatterings in the quark-gluon plasma. To arrive at this conclusion, I go beyond existing approaches in two aspects: (i) by calculating the collision probability beyond leading-log accuracy, taking into account the momentum dependence of...
