Rapidity and transverse momentum structure inπ + andK + collisions with Al and Au nuclei at 250 GeV/c

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

An analysis is presented of the rapidity and transverse momentum distributions and of the nuclear stopping power in collisions ofπ + andK + mesons with Al and Au nuclei at 250 GeV/c. The experimental results are compared to predictions of the additive quark model and the dual parton model. The AQM offers an overall consistent description of the data in this experiment. The DPM reproduces reasonably well the rapidity spectra in the central and projectile fragmentation regions, but fails to describe the nuclear stopping power.
