Inclusive Single-Particle Production at 90° in the Center-of-Mass System for Nuclear Targets and 28.5-GeV/cIncident Protons

Abstract

The invariant cross section for the inclusive production of ${\pi }^{+}$, ${\pi }^{-}$, $K^{+}$, $K^{-}$, $p$, and $\overline{p}$ is presented for proton-nucleon interactions at $p_{\mathrm{lab}}=28.5\mathrm{}$ GeV/c. Beryllium, titanium, and tungsten targets were used and the yields were extrapolated to $A=1\mathrm{}$ using the power law $\sigma \sim A^{\alpha }$. The exponent $\alpha$ increases with $p_T$, except for protons. The $p_T$ dependence of the cross sections is compared with a simple fireball model.
