Performance of the Muon Identification at LHCb

The performance of the muon identification in LHCb is extracted from data using muons and hadrons produced in $J/\psi \to \mu^+ \mu^-$, $\Lambda ^0 \to p\pi^-$ and $D^{\star +} \to \pi^+ D^0(K^- \pi^+)$ decays. The muon identification procedure is based on the pattern of hits in the muon chambers. A...

description The performance of the muon identification in LHCb is extracted from data using muons and hadrons produced in $J/\psi \to \mu^+ \mu^-$, $\Lambda ^0 \to p\pi^-$ and $D^{\star +} \to \pi^+ D^0(K^- \pi^+)$ decays. The muon identification procedure is based on the pattern of hits in the muon chambers. A momentum dependent binary requirement is used to reduce the probability of hadrons to be misidentified as muons to the level of 1%, keeping the muon efficiency in the range of 95-98%. As further refinement, a likelihood is built for the muon and non-muon hypotheses. Adding a requirement on this likelihood that provides a total muon efficiency at the level of 93%, the hadron misidentification rates are below 0.6%.
