Antiproton physics at GSI: Studying the physics of hadronic matter

GSI/Darmstadt is planning a major upgrade of its accelerator and experimental facilities. One of the main components of the proposed GSI-upgrade is a storage ring, in which beams of antiprotons with unprecedented quality and intensity will be available with beam momenta up to 15 GeV/c. At this facility a wide physics program is planned to investigate the structure of hadrons in the charmonium mass range, with the goal to develop a better understanding of the transition from quarks and gluons to hadrons as effective degrees of freedom. An overview of the physics program and the detector system envisioned for this project are presented.Received: 30 September 2002, Published online: 22 October 2003PACS: 13.75.-n Hadron-induced low- and intermediate-energy reactions and scattering (energy GeV) - 25.43. + t Antiproton-induced reactionsJ.
