Search for the Standard Model Higgs boson in WH -> lnubb and H -> WW(*) -> lnulnu channels at ATLAS

TL;DR

This paper reports on the search for the Standard Model Higgs boson in specific decay channels using ATLAS data, finding no evidence but setting exclusion limits in certain mass ranges.

Contribution

First search results for the Higgs boson in the WH -> lnubb and H -> WW(*) -> lnulnu channels at 7 TeV with ATLAS, providing exclusion limits.

Findings

No evidence for the Higgs boson in the analyzed channels.

Excludes Higgs mass range 158-186 GeV at 95% CL in H -> WW(*) channel.

WH -> lnubb channel not yet sensitive to the Standard Model Higgs.

Abstract

Results for the Standard Model Higgs boson search by the ATLAS experiment in the WH -> lnubb and H -> WW(*) -> lnulnu channels are presented. The results are based on 1.04 fb^-1 of data from pp collisions at sqrt(s) = 7 TeV produced by the LHC in 2011. No evidence is found for the Standard Model Higgs boson in either decay mode. The WH -> lnubb channel is not yet sensitive to the Standard Model Higgs, while the H -> WW(*) -> lnulnu channel excludes the Standard Model Higgs in the range of 158 < m_H < 186 GeV at the 95% confidence level.
