Some Aspects of Single-Particle and Two-Particle Inclusive Reactions in12.7−GeVcK+pand7−GeVcπ+pCollisions

Abstract

We present single-particle momentum spectra for ${\pi }^{-}$, $K^0$, ${\overline{\Lambda }}^0$, and ${\Lambda }^0$ particles produced in $K^{+}p$ collisions at 12.7 $\frac{\mathrm{GeV}}{c}$, and for ${\pi }^{-}$ mesons produced in ${\pi }^{+}p$ collisions at 7 $\frac{\mathrm{GeV}}{c}$. We examine the correlations between the transverse and longitudinal momentum components of these particles and compare them to those expected as a result of momentum conservation alone. We also investigate the transverse-momentum correlations in two-particle inclusive reactions and discuss the underlying kinematic constraints on these correlations.
