A new review of excitation functions of hadron production in $pp$ collisions in the NICA energy range

Abstract

Data on hadron multiplicities from inelastic proton-proton interactions in the energy range of the NICA collider have been compiled. The compilation includes recent results from the NA61/SHINE and NA49 experiments at the CERN SPS accelerator. New parameterizations for excitation functions of mean multiplicities $⟨{\pi }^{\pm }⟩$, $⟨K^{\pm }⟩$, $⟨K_S^0⟩$, $⟨\Lambda ⟩$, $⟨p⟩$, $⟨\bar{p}⟩$ are obtained in the region of collision energies $3<\sqrt{s_{NN}}<31$ GeV. The energy dependence of the particle yields, as well as variation of rapidity and transverse momentum distributions are discussed. A standalone algorithm for hadron phase space generation in pp collisions is suggested and compared to model predictions using an example of the PHQMD generator.
