The PANDA physics program
The physics program of PANDA covers variuos topics in hadron and
nuclear physics which can be addressed by studying the interaction of
antiprotons with nucleons and nuclei - the confinement of quarks within
hadrons, the origin of the mass of hadrons, self-interaction among the
exhange particles of the strong interaction, the gluons. With the
antiproton beam available at HESR, a broad range of hadrons can be
accessed:
PANDA's menu:
- Charmonium
The precision spectroscopy of all charmonium states with mass, width,
decay branches, is a key experiment to be done at PANDA. From that,
information on the quark confining potential can be extracted.
- Gluonic excitations: charmed hybrids, glueballs
Another important topic is the search for objects like charmed hybrids
and glueballs as they are predicted by QCD. PANDA will extend the
search for those objects into the charmonium mass range (3 to 5
GeV/c²), with high statistics and spin-parity analysis in fully
exclusive measurements.
- Charm in nuclei
Furthermore, the search for in-medium-modifications of hadrons (mesons)
and their possible relation to a (partial) restoration of chiral
symmetry in the nuclear medium will be persued, especially for mesons
containing open or hidden charm, which will shed light on the gluon
contribution in this sector.
- (Double) Hypernuclei
At PANDA, double and single Lambda hypernuclei can be produced
abundantly. An experiment with precision gamma ray spectroscopy of
hypernuclei for extracting information on their structure,
hyperon-nucleon and hyperon-hyperon interaction is planned. In
addition, Omega atoms can be formed and studied.
- Open Charm, GPD's, CP violation, transversity, timelike EM form factors
These are additional topics which can be studied at PANDA, some of them
need the HESR running at highest luminosity and thus are planned for a
later stage of the program.
