COMPASS Hadron Program

Boris Grube (München)

COMPASS is a multi-purpose fixed-target experiment at the CERN Super
Proton Synchrotron aimed at studying the structure and spectrum of
hadrons using high-intensity muon and hadron beams with energies ranging
from 160 to 190 GeV. One main goal is the search for new hadronic states
that are predicted by models and also recent lattice QCD calculations.
These states have exotic properties interpreted as excited gluonic field
configurations (hybrids) or even pure gluonic bound states (glueballs).

With its high-rate capability, large acceptance and high resolution the
COMPASS experiment is an excellent device to study the spectrum of
light-quark mesons in diffractive and central production reactions up to
masses of about 2.5 GeV. The setup is able to measure final states with
charged as well as neutral particles, so that resonances can be studied
in different reactions and decay channels.

COMPASS has acquired large data sets using 190 GeV positive and negative
hadron beams on various targets. The presented overview of the first
results from this data set focuses in particular on the search for
spin-exotic mesons in diffractively produced final states.
