Spectroscopy of Exotics at PANDA — •Bernhard Roth — Ruhr-Universität Bochum, 44780 Bochum
With the PANDA experiment at the future facility FAIR in Darmstadt
pp annihilations will be investigated with very high
luminosity and highest precision over a wide p momentum range
of 1.5−15GeV/c. One of the main topics of the physics
program is the spectroscopy of hadrons including the search for exotic
matter. Exotic glue ball states are predicted by QCD based models and
lattice QCD calculations. The f0(1500), observed in pp
annihilation by the Crystal Barrel Collaboration at LEAR and others,
is debated to be an admixture of the glue ball ground state and
conventional qq states. Motivated by this observation it is
believed that gluon rich processes in pp annihilation events
are a good source for the production of glue balls. In conjunction
with the ability of the PANDA detector to reconstruct final states
including charged and neutral particles with good coverage of the
solid angle, this offers excellent opportunities for the search for
glue balls. In particular higher mass states are accessible with
PANDA. Here the results of Monte Carlo studies of the production of
glue balls in the mass range of 2400−3700MeV /c2 decaying
to φφ in exclusively reconstructed pp→φφπ0
and pp→φφη events are presented.
