Search for narrow resonances in the b -tagged dijet mass spectrum in proton-proton collisions at s =8 TeV

A search for narrow resonances decaying to bottom quark-antiquark pairs is presented, using a data sample of proton-proton collisions at ffiffi s p ¼ 8 TeV corresponding to an integrated luminosity of 19.7 fb−1. The search is extended to masses lower than those reached in typical searches for res...
