Precision hadron spectroscopy in the charmonium mass region using antiproton annihilation
- Stefan Meyer Institut, Austrian Academy of Sciences, Vienna (Austria)
In contrast to systems at high momentum transfer where high accuracy predictions based on QCD can be made, several essential phenomena are still quantitatively unsettled in strongly interacting systems with low momentum transfer. These phenomena include quark confinement, existence of hadrons other than mesons and baryons, and the generation of the mass of hadrons. Hadronic states provide an intrinsically ideal system to address these issues. In particular, the spectroscopy of states with charm quark content provide a window of opportunity between the chiral and the heavy quark limits. Such states can be produced in copious numbers in antiproton-proton annihilation at the appropriate energy. Beams of antiprotons with unsurpassed brilliance will be available with momenta between 1.5 and 15 GeV/c at the new FAIR facility in Darmstadt, Germany. The combination of stochastic and electron phase space cooling will allow spectroscopy measurements with about 50 keV mass resolution and up to 1032 cm-2s-1 luminosity. These studies will be performed with the PANDA detector that is to be located inside the High Energy Storage Ring. This general purpose detector is a magnetic spectrometer with nearly 4{pi} acceptance for charged and neutral particles. An overview of the physics program and the detector will be presented.
