Pomeron-pomeron cross section from inclusive production of a central cluster in quasi-elastic π+ p andK + p scattering at 250 GeV/c

  • Published:

Abstract

Meson-nucleon quasi-elastic scattering is studied with (semi) inclusive production of a central hadron cluster. The dominant mechanism of central cluster production is double pomeron exchange. The cross section is (39±5±8) μb and (24±6±3) μb for pion and kaon induced reactions, respectively. An estimate of the pomeron-pomeron total cross section σpp is extracted in the interval\(4m_\pi< \sqrt {S_{pp} }< 2GeV\). While σpp=0.45±0.10mb is obtained in thef 2(1270) region, an almost constant cross section with an average of σpp=0.16±0.02mb is observed outside thef 2 region.
