b-tagging in the High Level Trigger

description A number of techniques exist in the CMS reconstruction framework that reduce the computing cost of track reconstruction. In this note, the b-tagging potential of these algorithms is discussed. The performance of an inclusive b-jets trigger is investigated. It is found that use of the b-tagging information can significantly improve the HLT efficiency of the inclusive jets stream for fully-hadronic final states. The most relevant physics case is given by top pairs with fully hadronic decays, where the b jets streams yield a signal efficiency of 15 %.
