MSSM Higgs bosons are the most promising way to discover Higgs physics at hadronic colliders since their cross section is enhanced compared to that of the Standard Model. In this talk I will present SUSY Higgs bounds on the [tan beta ; MA] plane in light of the uncertainties affecting the theoretical predictions at the Tevatron and the LHC.

This presentation reviews the search for the Standard Model Higgs boson at the D0 experiment with the final state containing two taus and at least two jets. Data from Run 2b of the D0 experiment are used with an integrated luminosity of 4.3 1/fb. This final state is sensitive the production mechanisms gluon gluon fusion, vector boson fusion, and associated Higgs production with a W or Z,...

We present a search for the standard model (SM) Higgs boson optimized
in the decay channel $H\rightarrow W^+W^-$, where both W bosons decay
leptonically. The final state considered contains dileptons
$(ee,\mu\mu,e\mu)$ and large missing transverse energy from the
neutrinos. A multivariate analysis is used to supress the
background. No signifiant excess above the SM background has...

We present a measurement of the lepton charge asymmetry in pp->W->lnu decays at sqrt(s)=7 TeV with the CMS detector at the LHC. Results are presented corresponding to 36 pb^-1 of integrated luminosity for both the electron and muon channels in 6 bins of lepton pseudorapidity up to |eta|=2.4 and |eta|=2.1 respectively. The measurements are compared with theoretical predictions and the results...

The measurement of the inclusive cross section for W+gamma production is presented based on 36 pb-1 of data acquired with the CMS detector from 7 TeV LHC collisions in 2010. Comparisons are made with the predictions of the standard model. The W bosons are identified through their leptonic decays to electrons and muons. The W+gamma cross section is sensitive to anomalous triple-gauge couplings...

With approximately 35/pb of LHC proton-proton collision data collected by CMS we study the Drell-Yan process qqbar -> Z -> l+l-. Differential cross sections with respect to the invariant mass, rapidity, and transverse momentum are presented. The forward-backward asymmetry is measured as a function of the di-lepton invariant mass, and an analysis of the fully differential distribution leads to...

A study of Z -> tau tau decays has been performed with the ATLAS experiment at the LHC. The channel with one tau lepton decaying into an electron or muon and the second one into hadrons has been analyzed. The study is based on a data sample corresponding to an integrated luminosity of 8.3 pb-1 for the electron channel and 8.5 pb-1 for the muon channel, at a proton-proton centre-of-mass energy...
