    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. © 2013 CERN.
