A prospective analysis for the search of the Standard Model (SM) Higgs boson with the CMS detector is presented in the context of the early LHC data. The aim is to establish an analysis strategy for inclusive production of the Higgs boson…
We briefly summarize some searches for Higgs bosons with a mass of m_phi <= 110 GeV at LEP and the LHC. We discuss a possible signal in the diphoton decay mode at m_phi = 96 GeV as reported by CMS, together with a 2 sigma hint in the bb…
Searches for Higgs boson at the LHC have excluded standard model (SM) Higgs boson mass in the range between 127 GeV to 600 GeV. With a fourth generation, the excluded range is wider. To close the windows between 114 GeV to 127 GeV, the mode…
We present a search for the standard model Higgs boson in H->WW(*), decays with ee, emu and mumu final states in p anti-p collisions at a center-of-mass energy of S**(1/2) = 1.96-TEV. The data, collected from April 2002 to June 2004 with…
A search for a Higgs boson in the decay channel ${\rm H} \rightarrow {\rm ZZ}^{(*)}$ with each Z boson decaying to an electron or muon pair is presented using pp collisions from the LHC at $\sqrt s$ = 7 TeV. The data analyzed correspond to…
Higgs boson searches are commonly considered one of the main objectives of particle physics nowadays. The latest results obtained by the CDF and D0 collaborations are presented here when searching for Higgs boson decaying into a W-boson…
A search for the Higgs boson in H->WW->ee and H->WW->mu+tau decays in ppbar collisions at a center-of-mass energy of sqrt(s)=1.96 TeV is presented. The data have been collected by the Run II DO detector. In order to maximize the sensitivity…
Recent searches conducted at the Fermilab Tevatron for the Higgs boson in the diphoton decay channel are reported using 7.0 fb$^{-1}$ and 8.2 fb$^{-1}$ of data collected at the CDF and D0 experiments, respectively. Although the standard…
We calculate four-fermion decays of a Higgs boson via $WW$ and/or $ZZ$ intermediate states for Higgs masses below $m_W$. We examine models with a doubly-charged Higgs boson $H^{++}$ and show that the four-fermion decay is the dominant mode…
A search for a heavy Higgs boson in the H to WW and H to ZZ decay channels is reported. The search is based upon proton-proton collision data samples corresponding to an integrated luminosity of up to 5.1 inverse femtobarns at sqrt(s) = 7…
A very simple and transparent way for the mass definition of a new boson, probably Higgs (H), observed at LHC, decaying into 4 leptons, is presented. The obtained mass of H is 125.5+/-0.4 GeV with today statistics.
We reconsider observables for discovering a heavy Higgs boson (with m_h > 2m_W) via its di-leptonic decays h -> WW -> l nu l nu. We show that observables generalizing the transverse mass that take into account the fact that both of the…
Recent LHC searches have not found a clear signal of the Higgs boson h of the standard model (SM) with three or four families in the mass range m_h = 120-600 GeV. If the Higgs had an unexpectedly large invisible branching ratio, the…
A search for a Higgs boson in the four-lepton decay channel H to ZZ, with each Z boson decaying to an electron or muon pair, is reported. The search covers Higgs boson mass hypotheses in the range 110 < mH < 600 GeV. The analysis uses data…
Recent results obtained by the CDF and D0 collaborations are presented here. These Tevatron Higgs searches look for a Standard Model (SM) Higgs boson decaying into W-boson pairs, with the W-bosons decaying into electron-neutrino or muon…
A search for the Higgs boson in H -> WW -> ll(l = e, mu) decays in ppbar collisions at a center-of-mass energy of sqrt{s}=1.96 TeV is presented. The data have been collected by the Run II DO detector between April 2002 and June 2008,…
A search for the Standard Model Higgs boson in the H -> WW(*) -> l nu l nu (l = e, mu) decay mode is presented. The search is performed using proton-proton collision data corresponding to an integrated luminosity of 4.7 /fb at a…
Direct and indirect searches of the Higgs boson suggest that 113 GeV $\lesssim m_H \lesssim$ 170 GeV is likely. With the LEP era over and the Tevatron Run II search via $p\bar p \to WH+X$ arduous, we revisit a case where $WH$ or $ZH +$ jets…
The recent discovery of a new boson at the LHC, which resembles a SM-like Higgs boson with $m_h=125$ GeV, is starting to provide strong guidelines into SUSY model building. For instance, the identification of such a state with the lightest…
We investigate the possible enhancement to the discovery of the heavy Higgs boson through the possible fourth SM family heavy neutrino. Using the channel h-> v4 v4->mu W mu W-> mu j j mu j j, it is found that for certain ranges of Higgs…
