Charged-particle (pseudo)rapidity distributions ine+e−,pp¯, andAAcollisions at high energies

A unified formula which describes the (pseudo)rapidity distributions of charged particles produced in high energy collisions is presented. The calculated results are compared and found to be in agreement with the experimental data of ${e}^{+}{e}^{\ensuremath{-}}$, $p\overline{p}$, and $AA$ collisions at high energies.
