Title: Muon identification with Muon Telescope Detector at the STAR experiment

Abstract

The Muon Telescope Detector (MTD) is a newly installed detector in the STAR experiment. It provides an excellent opportunity to study heavy quarkonium physics using the dimuon channel in heavy ion collisions. In this paper, we report the muon identification performance for the MTD using proton-proton collisions at s =500 GeV with various methods. The result using the Likelihood Ratio method shows that the muon identification efficiency can reach up to ~90% for muons with transverse momenta greater than 3 GeV/c and the significance of the J / ψ signal is improved by a factor of 2 compared to using the basic selection.
