Search for pair production of new physics resonances decaying to a top quark and jet in the lepton+jets decay channel
Abstract: A search is performed for a pair-produced excited top~quark, t, that decays to a top~quark and a gluonusing data collected by the CMS detector from pp collisions at s=8\TeV. The search is performed using events that have a single isolated muon or electron, missing transverse momentum, and at least six jets, one of which must be identified as originating from the fragmentation of a b~quark. The data analyzed correspond to an integrated luminosity of 19.6\fbinv. No significant excess is observed and we set a lower limit on the t-quark mass of \GeVcc$ at 95\% confidence level.
