Bose Distribution and Scaling Law

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