Abstract:
The results of a search for pair-produced vector-like quarks with charge −13 are presented. The analysis was performed using a dataset of pp collisions at √s=8 TeVcollected with the CMS detector and corresponding to an integrated luminosity of 19.6 fb−1. Events with a same-sign lepton pair and hadronic activity are selected and no excess above expected Standard Model backgrounds is observed. The results are used to set limits on the mass of the b′ quark as a function of its branching ratio to tW, bZ and bH. The data excludes a b′ quark with mass less than 800 GeV if the decay is to a top and W exclusively.
