Inclusive photoproduction of single charged particles at highp T

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

Single charged-particle inclusive cross sections for photon, pion and kaon beams on hydrogen at the CERN-SPS are presented as functions ofp T andx F . Data cover the range 0.0<p T <5.0 GeV/c and 0.0<x F <1.0 at incident momenta from 70 to 170 GeV/c. The comparison between photon- and hadron-induced data indicates a relative excess of particles withp T >1.6 GeV/c for the photon-induced data. Using the hadron-induced data to estimate the hadronic behaviour of the photon, the difference distributions and ratios of cross sections are a measure of the contribution of the point-like photon interactions. The data are compared with QCD calculations and show broadly similar features.
