چکیده
We combine searches by the CDF and D0 Collaborations for the associated production of a Higgs boson with a W or Z boson and subsequent decay of the Higgs boson to a bottom-antibottom quark pair. The data, originating from Fermilab Tevatron pp collisions at √s = 1.96 TeV, correspond to integrated luminosities of up to 9.7 fb(-1). The searches are conducted for a Higgs boson with mass in the range 100-150 GeV/c(2). We observe an excess of events in the data compared with the background predictions, which is most significant in the mass range between 120 and 135 GeV/c(2). The largest local significance is 3.3 standard deviations, corresponding to a global significance of 3.1 standard deviations. We interpret this as evidence for the presence of a new particle consistent with the standard model Higgs boson, which is produced in association with a weak vector boson and decays to a bottom-antibottom quark pair.

Strangephilic Higgs Bosons in the MSSM
We suggest a new CPX-derived scenario for the search of strangephilic MSSM Higgs bosons at the Tevatron and the LHC, in which all neutral and charged Higgs bosons decay predominantly into pairs of strange quarks and into a strange and a charm quark, respectively. The proposed scenario is realized within a particular region of the MSSM parameter space and requires large values of tanβ, where thr...
متن کاملTheoretical Status of Higgs Production at Hadron Colliders in the Standard Model
The search for the Higgs boson, the last missing particle in the Standard Model (SM) responsible for the electroweak symmetry breaking, is a primary goal of the CERN Large Hadron Collider (LHC), and is a central part of Fermilab’s Tevatron program. In the Standard Model, mass generation is triggered by the Higgs mechanism, which predicts the existence of one scalar particle, the Higgs boson [1]...
متن کاملHiggs particle detection using jets.
We study the possibility of detecting the Higgs boson in the intermediate mass range via its two jet channel. We consider only Higgs bosons produced in association with a t ¯ t pair. Both t and ¯ t are required to decay semileptoni-cally to reduce the QCD background. The signal is compared with the main background, t ¯ t + 2 jets, after appropriate cuts. A sizable signal above background is see...
متن کاملSearches for electroweak neutralino and chargino production in channels with Higgs, Z, and W bosons in pp collisions at 8 TeV
Searches for supersymmetry (SUSY) are presented based on the electroweak pair production of neutralinos and charginos, leading to decay channels with Higgs, Z, andW bosons and undetected lightest SUSY particles (LSPs). The data sample corresponds to an integrated luminosity of about 19.5 fb−1 of proton-proton collisions at a center-of-mass energy of 8 TeV collected in 2012 with the CMS detector...
متن کاملSearches for a High Mass Higgs Boson at the Tevatron
Recent results obtained by the CDF and DØ 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 neutrino final states. In the mass range of 135 GeV/c to 200 GeV/c, the SM Higgs decays prominently into W-boson pairs. The presented results are based on an in...
متن کاملHiggs-Boson Production in Association with a Single Bottom Quark
Higgs bosons from an extended Higgs sector, such as a two-Higgs-doublet model, can have greatly enhanced coupling to the bottom quark. Producing such a Higgs boson in association with a single high-pT bottom quark via gb → hb allows for the suppression of backgrounds. Previous studies have instead used gg, qq̄ → bb̄h as the production mechanism, which is valid only if both b quarks are at high pT...
