The first European Strategy for Particle Physics was adopted by CERN Council in July 2006. Since then the physics landscape has evolved in an exciting way, and a complete update of the strategy has been initiated end of 2011, with broad involvement of the community during 2012. The main issues and highlights from the proposed new strategy statements, which will still have to be formally...

In view of the discovery of a new boson by the ATLAS and CMS collaborations at the LHC, we present an update of the global Standard Model (SM) fit to electroweak precision data. Assuming the new particle to be the SM Higgs boson, all fundamental parameters of the SM are known allowing, for the first time, to overconstrain the SM at the electroweak scale and assert its validity.
Within the SM...

The usual SUSY fit requirements today include direct limit on SUSY searches, relic abundance of Dark matter, direct DM searches, Higgs mass, rare decays (including B->mumu) and Higgs decay branching ratios. Assumimg the latter ones are close to that of the SM one can fit all these requirements in the MSSM, albeit with heavy stops. The NMSSM provides much wider possibilities including varying...

In this talk, the latest results from CMS and ATLAS on searches for gluino induced and direct third generation SUSY production, in a variety of complementary final state signatures and methods, will be presented using up to 20/fb of data from the 8 TeV LHC run of 2012. SUSY models with relatively light top and bottom squarks are particularly appealing, especially given the recent Higgs-like...

The Large Hadron Collider has extended the reach of particle-physics experiments with a potential for discovery of new physics at the TeV scale. Many models of physics beyond the Standard Model predict new particles with long lifetimes. Examples include supersymmetry with R-parity violation, suppressed decays of the next-to-lightest supersymmetric particle, or models with hidden sectors. The...

We show that, in supersymmetry with extra singlets, it is easy and
natural to obtain a mass of the BEH scalar of ~125 GeV, well above M_Z.
Moreover the signal rate in the gamma gamma channel can be enhanced
w.r.t. the Standard Model for several reasons. These properties persist
in various singlet extensions of the MSSM, which are briefly scetched.
Correlations among signal rates in...

With the discovery of the Higgs boson by the ATLAS and CMS collaborations, all the constituents of the Standard Model (SM) of particle physics have been observed. Despite its success, the SM leaves many questions unanswered and that has motivated the many models of physics beyond the SM. These models predict a wide range of new phenomena that is accessible at the LHC. This talk will present...

It was shown recently that the original SU(5) gauge theory proposed by Georgi and Glashow,
augmented with an adjoint fermionic multiplet, is compatible both with neutrino masses
and gauge coupling unification. In particular, the latter predicts the existence of light electroweak triplet states with masses at the TeV scale. We are going to report in talk about the correlation between the...

In this talk, the latest results from the ATLAS and CMS experiments on searches for extra-dimensions, top-antitop resonances, fourth generation signatures and leptoquarks will be presented. The presented searches are performed using proton-proton collisions data at a centre-of-mass energy of 7 and 8 TeV. A large variety of final states are studied, probing many possible extensions of the...

With the discovery of a Higgs-like resonance at ATLAS and CMS, the understanding of the electroweak symmetry breaking origin seems a much closer goal. A strong dynamics at relatively low scales is still a good candidate. In this talk, the complete effective Lagrangian up to d<6 will be presented, both for the gauge and the flavour sector. Interesting features in the flavour phenomenology will...
