© 2013, CERN for the benefit of the ATLAS collaboration. A search for a charged Higgs boson (H<sup>+</sup>) in tt decays is presented, where one of the top quarks decays via t →H <sup>+</sup> b, followed by H <sup>+</sup> → two jets (cs). 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<sup>−1</sup>. 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 <sup>+</sup> masses between 90 GeV and 150 GeV, assuming B(H <sup>+</sup>→cs) = 100 %.
