Description
The results of a search for an excited bottom-quark b⁎ in pp collisions at √(s)=7 TeV, using 4.7 fb−1 of 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
