Abstract
A search for a charged Higgs boson (H[superscript +]) in t[bar over t] decays is presented, where one of the top quarks decays via t → H[superscript +]b, followed by H[superscript +] → two jets (c[bar over s]). The other top quark decays to Wb, where the W boson then decays into
a lepton (e/μ) and a neutrino. The data were recorded in pp collisions at √s = 7 TeV by the ATLAS detector at the LHC in 2011, and correspond to an integrated luminosity of 4.7 fb[superscript −1]. With no observation of a signal, 95 % confidence level (CL) upper limits are set on the decay branching ratio of top quarks to charged Higgs bosons varying between 5 % and 1 % for H[superscript +] masses between 90 GeV and 150 GeV, assuming B(H[superscript +] → c[bar over s]) = 100 %.
