Search for single vector-like B quark production and decay via B → bH(bb¯) in pp collisions at s = 13 TeV with the ATLAS detector

A search is presented for single production of a vector-like B quark decaying into a Standard Model b-quark and a Standard Model Higgs boson, which decays into a bb¯$$ b\overline{b} $$ pair. The search is carried out in 139 fb−1 of s$$ \sqrt{s} $$ = 13 TeV proton-proton collision data collected by t
