Search for a vector-like quark with charge 2/3 in t+Z events
Read the paper: EXO-11-005 In this Letter, CMS describes a search for a kind of fourth-generation T quark with charge 2/3. The search for T-antiT pairs was performed in events that had a pair of oppositely charged leptons (l+l−) as well as an additional isolated charged lepton.
