Bose Distribution and Scaling Law

Abstract

Properties of a two-parameter Bose-type distribution have been investigated using data on $\ensuremath{\pi}$ and $K$ mesons of inclusive $p\ensuremath{-}p$ collisions from 12 to 30 GeV/c. It is found that the temperature $T$ is characteristic of the particle emission: ${T}_{\ensuremath{\pi}}>{T}_{K}$, and $T$ for ${\ensuremath{\pi}}^{\ensuremath{-}}$ is about 5 MeV higher than that of ${\ensuremath{\pi}}^{+}$. The scaling behavior is found to hold for both $\ensuremath{\pi}$ and $K$ for incident lab momentum above 20 GeV/c.
