Search for single production of vector-like quarks decaying to a b quark and a higgs boson

A search is presented for single production of heavy vector-like quarks (B) that decay to a Higgs boson and a b quark, with the Higgs boson decaying to a highly boosted bb pair reconstructed as a single collimated jet. The analysis is based on data collected ¯ by the CMS experiment in proton-prot...
