Meson production inp+U, O+U and S+U interactions at 200 GeV/nucleon

  • Published:

Abstract

Meson production in proton, oxygen and sulphur interactions with uranium targets at 200 GeV/nucleon is studied. We measure the inclusive meson cross-section d σ/dP 2 T and its evolution fromp+U to S+U. The cross-section fitted with an exponential gives an inverse slopeP T0 of the order of 210 MeV/c. As a function of the neutral transverse energy,P T0 values show a slight rise followed by a plateau. The normalized difference (σ+−σ−)/σ− between positive and negative meson cross-sections is found to increase withE T .
