Recent measurements demonstrate charged hadron production in various collision systems, indicating theoretical model comparisons.
The paper presents recent PHENIX measurements of identified charged hadron production (π, K, p, β) in p+Al, He+Au, Cu+Au at √s = 200 GeV and in U+U at √s = 193 GeV. The measured values of p/π and β/π are compared with the predictions of the AMPT (string melting version) and PYTHIA/ANGANTYR program packages. The integral values of p/π, β/π, K/π, K/π as a function of the number of participating nucleons are presented.
