Abstract
The results of a search for charged Higgs bosons are presented. The analysis is based on 4.6 fb⁻¹ of proton-proton collision data at √s = 7 TeV collected by the ATLAS experiment at the Large Hadron Collider, using top quark pair events with a τ lepton in the final state. The data are consistent with the expected background from Standard Model processes. Assuming that the branching ratio of the charged Higgs boson to a τ lepton and a neutrino is 100%, this leads to upper limits on the branching ratio of top quark decays to a b quark and a charged Higgs boson between 5% and 1% for charged Higgs boson masses ranging from 90 GeV to 160 GeV, respectively. In the context of the mmax h scenario of the MSSM, tan β above 12–26, as well as between 1 and 2–6, can be excluded for charged Higgs boson masses between 90 GeV and 150 GeV.
