Higgs Search in $b\bar{b}$ Signatures at ATLAS and CMS

TL;DR

This paper reports on searches for the Standard Model Higgs boson decaying to bottom quark pairs using data from ATLAS and CMS at the LHC, setting upper limits on production cross sections at 7 and 8 TeV.

Contribution

It presents the first combined search results for Higgs to $b\bar{b}$ decays in association with vector bosons or top-quark pairs at the LHC, using data from both ATLAS and CMS.

Findings

Set 95% CL upper limits on Higgs production cross section times branching ratio.

Analyzed data from 7 TeV and 8 TeV collisions totaling up to 13.0 fb$^{-1}$.

Provided constraints on the Standard Model Higgs boson in the $b\bar{b}$ decay channel.

Abstract

We report on searches for the Standard Model Higgs boson decaying to $b \bar{b}$ in $pp$ collisions at the ATLAS and CMS experiments. These rely on signatures where the Higgs boson is produced in association with a vector boson or in association with a top-quark pair. Results are presented, based on $5.0~\mathrm{fb}^{-1}$ of $pp$ collision data at $\sqrt{s} = 7$~TeV and up to $13.0~\mathrm{fb}^{-1}$ of data at $\sqrt{s} = 8$~TeV collected by the LHC accelerator. These are expressed in terms of 95\% confidence level upper limits on the production cross section of the Standard Model Higgs boson times the branching ratio to decay to $b$-quark pair.
