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

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

The transverse momentum distributions for\(\rho ^0 (770),f_2 (1270),K*^0 (892),\bar K*^0 (892)\) and ϕ (1020) have been studied in thep 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 π− beam incident on a Be target. These distributions are well described by the functionp −nt withn∼8. A sample of simulated events from the Lund Monte Carlo in the same experimental conditions reproduces well the data.
