Exotic decays of heavy B quarks
2016
Journal of High Energy Physics
Heavy vector-like quarks of charge -1/3, B, have been searched for at the LHC through the decays B→ bZ, bh, tW. In models where the B quark also carries charge under a new gauge group, new decay channels may dominate. We focus on the case where the B is charged under a U(1)^' and describe simple models where the dominant decay mode is B→ bZ^'→ b (bb̅). With the inclusion of dark matter such models can explain the excess of gamma rays from the Galactic center. We develop a search strategy for
