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 {Mathematical expression}. While σpp=0.45±0.10mb is obtained in the f2(1270) region, an almost constant cross section with an average of σpp=0.16±0.02mb is observed outside the f2 region.
