The SM Higgs boson in the medium and high mass ranges has a large
branching ratio for decays to a pair of neutral weak bosons. Three
decay modes of the Z boson pair have been explored by ATLAS. One Z is typically produced on-shell, which can be tagged using leptonic decay products. The decay of the second Z(*) leads to three independent search channels: llqq, llvv and llll. Background...

We present a search for the Standard Model Higgs boson produced via the H->WW*->lvjj and H->ZZ*->4l processes at a center-of-mass energy of 1.96 TeV using up to 8.5 fb-1 of data collected with the D0 and CDF detectors at the Fermilab Tevatron collider. We search in events with either four charged leptons, or two jets, one charged lepton, and missing transverse energy. The four lepton channel...

Recent searches conducted at the Fermilab Tevatron for the Higgs boson in the diphoton decay channel are reported using 7.0/fb and 8.2/fb of data collected at the CDF and D0 experiments respectively. Although the standard model (SM) branching fraction is small, the diphoton final state is appealing due to better diphoton mass resolution compared with dijet final states. In addition, other...

Diphoton final state is one of the most sensitive channels to a Higgs search in the low mass region (115GeV-140GeV). The analysis is optimized to search for a Standard Model (SM) Higgs and dominates the SM Higgs combination in the mass range lower than 120GeV. Nevertheless, an inclusive search strategy adopted is also sensitive to find a low mass diphoton resonance that could be predicted by...

The dominant production mechanism for Standard Model (SM) Higgs boson is gg->h. However, in certain beyond the SM scenarios, Higgs production with bottom quarks can become dominant due to enhanced bottom quark Yukawa coupling. One such model is the Minimal Supersymmetric Standard Model (MSSM) where the bottom Yukawa coupling to Higgs bosons, including the SM-like Higgs, gets significantly...

In some supersymmetric (SUSY) models, a charged Higgs boson ($\rm H^\pm$) can decay into a chargino-neutralino ($\rm\chi^\pm_i \chi^0_j $) pair producing a final state containing three leptons (electron/muon) and missing transverse energy ($3\ell+E_{\mathrm{T}}^{\mathrm{miss}}$). Such a decay could provide extra sensitivity to the $\rm H^\pm$, especially in the region of SUSY parameter space...

The study of diboson production at high energy colliders tests the electroweak sector of the standard model (SM) and provides a sensitive probe of new physics beyond the SM. An important example is the production of a Higgs boson with mass greater than 140 GeV/c^2 which decays primarily to W boson pairs. The diboson decay channel where one W boson decays to leptons and the other vector boson...

We study the decays of the lightest Higgs boson within the exceptional

Theoretical knowledge of the low transverse momentum (pT) distribution of the Higgs boson, plays an important role in search strategies for the Higgs. In the region of low pT, much smaller than the Higgs mass, large logarithms spoil the perturbative expansion and must be resummed.
