Search for heavy top quark partners with charge 5/3 in the single-lepton final state in proton-proton collisions at $\sqrt{s}$ = 13 TeV

CMS Collaboration

A search for the pair production of a vector-like quark, X${}_{5/3}$, a heavy fermionic partner of the top quark with an electric charge of 5/3, is presented. The search is performed…
