Abstract (english)
The PHENIX experiment has performed a systematic study of identified charged-hadron (πœ‹Β±, 𝐾±, 𝑝, ‾𝑝) production at midrapidity in 𝑝+Al, 3He+Au, and Cu+Au collisions at βˆšπ‘ π‘π‘=200GeV and U+U collisions at βˆšπ‘ π‘π‘=193GeV. Identified charged-hadron invariant transverse-momentum (𝑝𝑇) and transverse-mass (π‘šπ‘‡) spectra are presented and interpreted in terms of radially expanding thermalized systems. The particle ratios of 𝐾/πœ‹ and 𝑝/πœ‹ have been measured in different centrality ranges of large (Cu+Au and U+U) and small (𝑝+Al and 3He+Au) collision systems. The values of 𝐾/πœ‹ ratios measured in all considered collision systems were found to be consistent with those measured in 𝑝+𝑝 collisions. However, the values of 𝑝/πœ‹ ratios measured in large collision systems reach the values of β‰ˆ0.6, which is a factor of β‰ˆ2 larger than in 𝑝+𝑝 collisions. These results can be qualitatively understood in terms of the baryon enhancement expected from hadronization by recombination. Identified charged-hadron nuclear-modification factors (𝑅𝐴𝐡) are also presented. Enhancement of proton 𝑅𝐴𝐡 values over meson 𝑅𝐴𝐡 values was observed in central 3He+Au, Cu+Au, and U+U collisions. The proton 𝑅𝐴𝐡 values measured in the 𝑝+Al collision system were found to be consistent with 𝑅𝐴𝐡 values of πœ™, πœ‹Β±, 𝐾±, and πœ‹0 mesons, which may indicate that the size of the system produced in 𝑝+Al collisions is too small for recombination to cause a noticeable increase in proton production.
