Simulation studies of the PANDA detector at GSI — •Carsten Schwarz — GSI, Darmstadt

A new international accelerator facility for beams of ions and antiprotons has recently been recommended [1] to be realized at the Gesellschaft für Schwerionenforschung in Darmstadt (GSI). The proposed facility opens up new avenues in basic and applied research, above all in the fields of nuclear, hadron, atomic and plasma physics. One part covers the installation of a High-Energy Storage Ring (HESR), in which antiprotons in an energy range between 1 GeV and 15 GeV can be stored. This will allow experiments, for example, concerning charmonium spectroscopy, the search for hybrids and glueballs and the interaction of hidden and open charm particles with nucleons and nuclei [2]. The PANDA [3] detector, which should meet all the requirements for such investigations, is subject to detailled Monte-Carlo studies, which are performed with the GEANT4 software package and two event generators. One, the Pluto++ event generator provides the physical signal observed by the different detector subsystems, the other, the DPM background event generator checks the significance of this signal. Different detector configurations are being tested for their suitability.
