Search for single production of a vector-like B' quark decaying to a top quark and a W boson in the single-lepton final state in proton-proton collisions at $\sqrt{s}$ = 13 TeV

A search is presented for the single production of a narrow-width vector-like B' quark that decays to a t quark and a W boson. This search targets a single-lepton final state, where a muon or electron originates either from the semileptonic decay of the t quark or from the leptonic decay of the W bo
