Single-particle distribution in hadron-nucleus scattering and the partition-temperature model

The partition-temperature model gives a good description of the single-particle pseudorapidity distribution in hadron-nucleus scattering. The parameters of the model can be summarized in simple phenomenological rules, one of which is that the effective target mass is approximately ν nucleon masses, where ν=A${\sigma }_{\mathrm{hh}}$/${\sigma }_{\mathrm{hA}}$ is the ‘‘number of collisions.’’
