The PANDA Experiment at FAIR — •Bernhard Ketzer for the PANDA collaboration — Technische Universität München, Physik Department, 85748 Garching, Germany
PANDA is a new detector at the antiproton storage ring HESR of FAIR to study fundamental questions of hadron physics at large distances using an intensive, cooled antiproton beam. Precision spectroscopy of hadrons containing strange and charm quarks in the mass range between 2 and 5 GeV/c2 is the key towards a complete understanding of the charmonium spectrum, especially above the DD threshold, and a firm establishment of gluonic excitations, like hybrids or glueballs, or multi-quark states. Modifications of spectral properties of charmed mesons in nuclear matter are expected to give insight into the mechanism of hadron mass generation by chiral symmetry breaking. Other topics to be studied at PANDA include measurements of J/ψ dissociation in nuclei, hypernuclei, time-like electromagnetic form factors, and open charm physics.
The efficient detection and identification of charmed hadrons requires a state-of-the-art spectrometer with high resolution and maximum solid angle coverage both for charged and neutral particles, and a flexible yet selective triggering and data acquisition system.
After a brief overview of the FAIR accelerator complex, I will discuss the physics questions to be addressed at PANDA, the requirements to the beam and detector resulting therefrom, and the present layout of the detector, including a more detailed description of a few of its key components.
