Production of thef 0 meson in the Double Pomeron Exchange reactionpp→ppπ+π−

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

Data are presented for the exclusive reaction pp → pp π+ π− at\(\sqrt s = 62GeV\) with two leading protons at large Feynman-x and a centrally produced π+;π− system. In this kinematical configuration one expects a substantial contribution from Double Pomeron Exchange, which is a potential source of glueballs. The experiment was performed at the CERN ISR using the Split Field Magnet spectrometer. In the mass range between 1,000 and 1,700 MeV/c2 the invariant mass distribution for the central π+;π− system exhibits a very significant signal for thef 0(1270) and no other obvious resonant states.
