Particle Identification in the PANDA-Experiment at FAIR — •Georg Schepers for the PANDA collaboration — Gesellschaft für Schwerionenforschung mbH Darmstadt, Germany

Highly luminous beams require detector systems with unprecedented PID (particle identification) capabilities. PANDA will use the antiproton beam of extrem intensity and quality provided by the new FAIR facility in the energy range of 1.5 to 15 GeV corresponding to the mass range of 0 to 6 GeV/c$^2$ and opens access to the heavier strange and charm quarks and to copius production of gluons to address fundamental questions in the fields of Quantum Chromodynamics and symmetries. A crucial part of this excellent tool is the particle identification (PID) in the light of an event rate of 2$\times$10$^7$/s with up to 10 reaction products at PANDA. The PID detectors studied including electromagnetic and hadronic calorimeters, Cherenkov detectors (from RICH and DIRC typ), MVD, TPC and muon counters and their performance in separation power will be presented. From the separation power, i.e. numbers of sigma between particle hypotheses, one deduces the percentage of correct identified and misidentified particles. Concepts for a Global PID analysis for PANDA are mentioned.
