The experimental results of the search for the Standard Model Higgs boson at the Large Hadron Collider (LHC) running at a centre-of-mass energy of 7 TeV are reported, based on a total integrated luminosity of up to 4.9 fb-1 collected by the ATLAS detector in 2011. The search combines several Higgs boson decay channels in the mass range from 110 GeV to 600 GeV and derives upper limits on the...

We present results from the search for a standard model Higgs boson using up to 10/fb of proton-antiproton collision data produced by the Fermilab Tevatron at a center-of-mass energy of 1.96 TeV. The data were recorded by the CDF and D0 Detectors between March 2001 and September of 2011. Updated results from many exclusive channels as well as the combined Tevatron search are presented.

The discovery of a neutral Higgs boson with large decay branching fraction to tau and muon pairs, as well as the discovery of a charged Higgs boson would represent a strong evidence of new physics beyond the Standard Model. The experimental results of the searches for the Higgs bosons beyond the Standard Model with the ATLAS detector are reported. The searches are based on an integrated...

Several types of new-physics models predict the existence of low-mass Higgs states. Previous BABAR searches for leptonic and invisible light-Higgs decays have excluded large regions of model parameter space. We present new searches for hadronic Higgs decays and for a dark-sector Higgs produced in association with a dark gauge boson.

In Beyond Standard Model (BSM) theories such as supersymmetry,
the electroweak symmetry breaking mechanism predicts one or
several Higgs bosons with different couplings and masses compared to the Standard Model one. We will present the constraints on BSM theories coming from searches for exotic Higgs bosons from the CDF and D0 collaborations at the Tevatron. In addition, other bump searches...

We present the implications of recent LHC results on some classes
of Z' and W' models. We also remark how the strongest bounds
(coming for example from searches for Z' -> dileptons and W' ->
lepton + neutrino) do not apply to some theoretically motivated
resonances, and discuss where signals from such states would
appear.

The addition of one or more heavy quarks is a natural extension to the Standard Model.
Fourth generation heavy quarks can be produced at the LHC at rates that can be observed in the 2011 data samples.
The talk presents results from searches\'a0performed by the ATLAS collaboration for fourth generation quarks decaying via several potential decay channels.

The OPERA neutrino experiment at the underground Gran Sasso Laboratory has measured the velocity of neutrinos from the CERN CNGS beam over a baseline of about 730 km with much higher accuracy than previous studies conducted with accelerator neutrinos. The measurement is based on high-statistics data taken by OPERA in the years 2009, 2010 and 2011. Dedicated upgrades of the CNGS timing system...

The LHC is closing in on the Minimal Supersymmetric Standard Model. The null results from superparticle searches, and the preliminary
evidence for a 124-126 GeV Higgs, severely constrain various popular minimal scenarios. In this talk I will review these constraints,
and point out how the LHC results can still be accommodated within the MSSM. The resulting superparticle mass spectra may...

We present results of searches for SUSY production at CMS in events
containing hadronic jets and missing energy. Various discriminants
based on the event kinematics are employed to suppress standard-model
backgrounds. The results are interpreted in the context of the Constrained
Minimal Supersymmetric Standard Model, and of a number of "simplified

We present results of searches for SUSY production at CMS in

single isolated leptons, Z bosons decaying to lepton pairs, non-resonant
same- and opposite-sign lepton pairs, and three or more isolated leptons.
The results are used to exclude previously unexplored regions of the
supersymmetric parameter space assuming R-parity...

Searches for supersymmetry at the LHC also embrace signatures from R-parity violating processes. These can be final states with resonant or non-resonant lepton flavour violation or multiple leptons. The talk presents recent results from searches for R-partity violation in events containing leptons based on data recorded in 2011 by the ATLAS detector.

We review the status of motivated beyond-MSSM scenarios in the light of the first searches at the LHC. In particular, we discuss the consequences for model building of a Higgs boson at about 125 GeV and of taking seriously the excess in the direct CP violation in the charm sector.

Supersymmetry with large mixing between left and right scalar fermions predicts that the lightest partners of the SM fermions belong to the third generation. Moreover, naturalness arguments favour stop masses not too far from that of the top quark.

Naturalness arguments for weak-scale supersymmetry favour supersymmetric partners of the Higgs and electroweak gauge bosons, so-called gauginos, with masses not too far from those of their Standard Model counterparts. Gauginos with masses less than a few hundred GeV can give rise to direct pair production rates at the LHC that can be observed in the data sample recorded in 2011 by the ATLAS...

We present results of searches for SUSY production at CMS in events
containing hadronic jets and missing energy. The tagging of heavy
flavor in the jets is used both to distinguish standard-model
components, and for sensitivity to those SUSY models that lead to
final states rich in heavy-flavored particles.
