Search for the SM Higgs decaying to a b-quark pair with ATLAS
Alberto Palma
TL;DR
This paper reports the first ATLAS search for the Standard Model Higgs boson decaying into b-quark pairs in the 110-130 GeV mass range, using 7 TeV collision data, with no evidence found but setting upper limits.
Contribution
It provides the initial ATLAS results for Higgs to b-quark pair decays in associated production channels at 7 TeV, establishing upper limits on production cross sections.
Findings
No evidence for Higgs production observed.
Upper limits set on Higgs production cross sections.
Results cover 110-130 GeV mass range.
Abstract
Summary of first ATLAS results is given for the Standard Model Higgs boson in the mass range 110 < mH < 130 GeV, when produced in association with a W/Z boson and decaying to a pair of b-quarks. No evidence for the Higgs boson production is observed in a dataset of proton-proton collisions at a center of mass energy of 7 TeV and corresponding to 1.04 fb-1 of integrated luminosity, recorded by the ATLAS experiment at the LHC in 2011. Upper limits on Higgs boson production cross sections for the channels considered are presented.
