Search for pair production of a new heavy quark that decays into a W boson and a light quark in pp collisions at s =8 TeV with the ATLAS detector

A search is presented for pair production of a new heavy quark (Q) that decays into a W boson and a light quark (q) in the final state where one W boson decays leptonically (to an electron or muon plus a neutrino) and the other W boson decays hadronically. The analysis is performed using an integrat...
