“…It is noticed that the two-or multi-component Erlang distribution has wide applications. In our previous work [55], this distribution was used to describe multiplicity, mass, transverse mass, transverse energy, and transverse momentum spectra of final-state particles in proton-antiproton and electron-proton (positron-proton) collisions, as well as excitation energy spectrum for selected events in nucleus-nucleus collisions at high energies. This distribution was also used to describe the event-by-event fluctuations in the multiplicity, the total transverse energy, the mean transverse energy, and the mean transverse momentum in nucleus-nucleus collisions at high energies [22], and to describe the production cross-section of projectile-like isotopes in nucleus-nucleus collisions at intermediate and high energies [23,24].…”
