Physics with ALICE Transition Radiation Detector

Measurements of heavy quarkonia states, such as J/Psi, Psi', gamma, gamma', and high P-T charged particles carry important information to characterize the quark gluon plasma produced in high energy heavy ion collisions at LHC. The ALICE Transition Radiation Detector (TRD) provides clear separation of electrons from the large background of pions and improves the tracking performance of ALICE central barrel detectors. The TRD also provides a fast trigger signal on high transverse momentum charged particles. In this paper we present the capabilities of heavy quarkonia reconstruction and jet trigger of TRD.
