Performance studies on the CBM TRD using J/Ψ

The Transition Radiation Detector (TRD) will be one of the key components of the CBM experiment. It will serve for particle tracking and for the identification of electrons and positrons. J/Ψ production in the dielectron channel is a unique physics process to study the performance of the TRD. In the framework of CBMRoot mixed samples of J/Ψ and background events are simulated in the detector setup. Then J/Ψ particles are reconstructed with the TRD and other tracking detectors in the same framework. The limit of the TRD hit resolution is studied using the ratio of reconstructed J/Ψ signal to background, which will hence provide useful information to determine the size of readout pads. Feasibility studies on triggering J/Ψ particles only with the TRD has also been performed using a stand-alone tracking method.
