Description
COMPASS is a multi-purpose fixed-target experiment at the CERN Super Proton Synchrotron. It is aimed at studying the spectrum of hadrons using high-intensity hadron beams with energies of 190 GeV. One main goal is the search for new hadronic states. These states may have exotic properties interpreted as multi-quark configurations (e.g. molecule-like objects), excited gluonic field configurations (hybrids), or even purely gluonic bound states (glueballs). COMPASS has acquired large data sets using positive and negative hadron beams on various targets. The presentation of the first results from the analysis of these data sets focuses in particular on the finding of a possible new light-quark resonance with surprising properties.
