Description
Meson production in proton, oxygen and sulphur interactions with uranium targets at 200 GeV/nucleon is studied. We measure the inclusive meson cross-section dσ/dPT2 and its evolution from p+U to S+U. The cross-section fitted with an exponential gives an inverse slope PT0 of the order of 210 MeV/C. As a function of the neutral transverse energy, PT0 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 with ET. (orig.)
