Isotropic Black-Body Boson Production and the Temperature of Hadronic Matter

Abstract

Inclusive ${\pi }^{+}$, ${\pi }^{-}$, and $K^0$ production from $11.8-\frac{\mathrm{GeV}}{c}$ $K^{+}p$ is isotropic in the center-of-mass system and obeys a Bose-Einstein distribution over a limited energy range. The values of the parameter $\mathrm{kT}$ are observed to be consistent with the pion mass.
