A time-based likelihood approach for the PANDA Barrel DIRC detector — Roman Dzhygadlo1, Klaus Götzen1, Grzegorz Kalicy1,2, Harphool Kumawat1,3, Maria Patsyuk1,2, Klaus Peters1,2, Carsten Schwarz1, Jochen Schwiening1, and •Marko Zühlsdorf1,2 for the PANDA collaboration — 1GSI Helmholtzzentrum für Schwerionenforschung GmbH, Darmstadt — 2Goethe-Universität Frankfurt — 3Bhabha Atomic Research Centre, Mumbai
The PANDA experiment at the future Facility for Antiproton and Ion Research in Europe GmbH (FAIR) at GSI, Darmstadt will study fundamental questions of hadron physics and QCD using high-intensity cooled antiproton beams with momenta between 1.5 and 15 GeV/c. Efficient Particle Identification (PID) for a wide momentum range and the full solid angle is required for reconstructing the various physics channels of the PANDA program. Hadronic PID in the barrel region of the PANDA detector will be provided by a DIRC (Detection of Internally Reflected Cherenkov light) counter. The design is based on the successful BABAR DIRC with several key improvements.
This contribution presents simulation studies of a barrel DIRC design based on wide radiator plates instead of narrow bars and a PID method using a time-based likelihood approach to make optimum use of the precision timing of this new counter.
