Abstract

The results of a search for an excited bottom-quark b^*in pp collisions at s=7 TeV, using 4.7 fb^-1of data collected by the ATLAS detector at the LHC are presented. In the model studied, a single b^*-quark is produced through a chromomagnetic interaction and subsequently decays to a W boson and a top quark. The search is performed in the dilepton and lepton+jets final states, which are combined to set limits on b^*-quark couplings for a range of b^*-quark masses. For a benchmark with unit size chromomagnetic and Standard Model-like electroweak b^*couplings, b^*quarks with masses less than 870 GeV are excluded at the 95% credibility level.
