Transverse momentum distributions for meson resonances at central rapidity andP T≧2 GeV/c

Abstract

The p t distributions for 0 (770), f 2 (1270), K 0 (892), K 0 (892) and ( 1020) have been studied in the p t region between 2 and 4 GeV/c and central rapidity. The data analysed come from the WA77 experiment at CERN with a 300 GeV/c beam incident on a Be target. The p t distributions are well described by the function p n t with n 8. A sample of simulated events from the Lund Monte Carlo in the same experimental conditions reproduces well the data.
