Search for a Standard Model Higgs boson decaying to b quarks and produced in association with Z/W bosons with the CMS detector

TL;DR

This paper reports a search for the Standard Model Higgs boson decaying to bottom quarks in association with W/Z bosons using CMS data at 7 TeV, setting upper limits on production cross sections.

Contribution

First search for Higgs to bb in association with W/Z bosons at 7 TeV with CMS, establishing upper limits on production cross sections for 110-135 GeV.

Findings

Expected upper limit at 115 GeV is 5.7 times the SM prediction.

Observed upper limit at 115 GeV is 8.3 times the SM prediction.

Set 95% confidence level upper limits on VH production cross section.

Abstract

A search for the standard model Higgs boson is performed in a data sample corresponding to an integrated luminosity of 1.1 fb$^{-1}$, recorded by the CMS detector in proton-proton collisions at the LHC with a 7 TeV center-of-mass energy. The following modes are studied: W($\mu \nu$)H, W(e$\nu$)H, Z($\mu \mu$)H, Z(ee)H and Z($\nu \nu$)H, with the Higgs decaying to bb pairs. 95% C.L. upper limits on the VH production cross section are derived for a Higgs mass between 110 and 135 GeV. The expected (observed) upper limit at 115 GeV is found to be 5.7 (8.3) times the standard model expectation.
