Particle physics theoretical and experimental studies

We present first results from a study of the exclusive reaction pp→pπ+π−p at √s=63 GeV with π+ and π− produced in the central region. This reaction has been suggested as a method of searching for gluonium states. The π+π− mass distribution shows rapid order of magnitude decreases in cross section at both 1000 MeV/c2 and 1500 MeV/c2. Further structure is observed above 2000 MeV/c2.
