We present a new scheme for tagging boosted heavy flavor jets called “µx tagging.” At the LHC, the primary method to tag b-jets relies on tracking their charged constituents. However, when highly boosted, track-based b-tags lose efficiency, and the probability to mistag light jets rises dramatically. Using muons from B hadron decay and defining a particular combination “x” of angular information and boost estimation, we find fairly flat efficiencies to tag b-jets, c-jets, light-quark jets, and light-heavy jets (containing B hadrons from gluon splitting) of ϵb = 14%, ϵc = 6:5%, ϵlight–light = 0:1%, and ϵlight-heavy = 0:5%, respectively. We demonstrate the usefulness of this new scheme by showing the reach for discovery of a leptophobic Z′ → bb̄ in the dijet channel.
