We report results of a study of the Standard Model Higgs boson discovery potential through the W-pair leptonic decay modes with the ATLAS detector at LHC at 14 TeV center-of-mass energy. We used MC samples with full detector simulation and reconstruction of the ATLAS experiment to estimate the ATLAS detection sensitivity for the reaction of pp→ H →WW → eνμν with no hard jet or two hard jets in ...

The recent discovery of a Higgs boson at the LHC is a milestone in the quest to understand electroweak symmetry breaking. It is an important particle because it is responsible for the Higgs mechanism by which all particles acquire mass. The existence of a particle with zero spin suggests the need for new physics beyond the standard model. Z  bosons are known to naturally exist in well-motivate...

New preliminary combined results from the LEP experiments on searches for the Higgs boson beyond the Standard Model are presented. The new determination of the top quark mass at the Tevatron in 2004 influences the interpretations of the LEP results in both, the Standard Model, and the Minimal Supersymmetric extension of the Standard Model. Higgs boson physics will also be a major research area ...

In 1996 the center-of-mass energy of the electron-positron collider LEP was increased above the threshold of two times the W-boson mass (MW) which made it possible to produce pairs of W-bosons in ee collisions and thus opened the opportunity for a precision determination of the W-boson mass and measurements of its couplings and decay branching ratios. A detailed review of measurements of the W-...

A key aim of the Large Hadron Collider (LHC) is to discover the Higgs boson, or to prove its non-existence, and hence elucidate the mechanism of mass generation and electroweak symmetry breaking. Current electroweak fits, together with the LEP exclusion limit, favour a light Higgs boson, i.e. one around 120 GeV in mass [1]. This mass region is particularly challenging for the LHC experiments, a...

We present a search for the standard model Higgs boson produced in association with a Z boson in data collected with the CDF II detector at the Tevatron, corresponding to an integrated luminosity of 9.45  fb(-1). In events consistent with the decay of the Higgs boson to a bottom-quark pair and the Z boson to electron or muon pairs, we set 95% credibility level upper limits on the ZH production ...

A search for particles with the same mass and couplings as those of the standard model Higgs boson but different spin and parity quantum numbers is presented. We test two specific alternative Higgs boson hypotheses: a pseudoscalar Higgs boson with spin-parity J^{P}=0^{-} and a gravitonlike Higgs boson with J^{P}=2^{+}, assuming for both a mass of 125  GeV/c^{2}. We search for these exotic state...

A precise determination of the W boson mass at the Fermilab Tevatron requires a theoretical calculation in which the effects of the initial-state multiple soft-gluon emission and the final-state photonic correction are simultaneously included. Here, we present such a calculation and discuss its prediction on the transverse mass distribution of the W boson and the transverse momentum distributio...

In this talk preliminary results of Higgs boson searches at LEP2 up to centre-of-mass energies of 183 GeV have been summarised. The main topics are searches for the Minimal Standard Model (MSM) Higgs boson and searches for neutral Higgs bosons of the Minimal Supersymmetric Standard Model (MSSM). No indication for Higgs production has been found. The experiments have published their Higgs search...

A summary of the Higgs boson searches by the ATLAS and CMS collabrations using 1 f b −1 of LHC data is presented, concentrating on the Standard Model Higgs boson. Both experiments have the sensitivity to exclude at 95% CL a Standard Model Higgs boson in most of the Higgs boson mass region between about 130 GeV and 400 GeV. The observed data allow the exclusion of a Higgs Boson of mass 155 GeV t...
