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=500Â GeV with various methods. The result using the Likelihood Ratio method shows that the muon identification efficiency can reach up to â¼90% for muons with transverse momenta greater than 3Â GeV/c and the significance of the J/Ï signal is improved by a factor of 2 compared to using the basic selection.
