Abstract

The paper presents systematic study of identified charged hadron ( \({{\pi }^{ \pm }}\) , \({{K}^{ \pm }}\) , \(p\) , \(\bar {p}\) ) production in \(p\)  + Al, 3He + Au, Cu + Au collisions at the energy \(\sqrt {{{s}_{{NN}}}} \) = 200 GeV and in U + U collisions at \(\sqrt {{{s}_{{NN}}}} \) = 193 GeV. The measured values of the invariant spectra as well as the ratios of proton to \(\pi \) -meson yields ( \({p \mathord{\left/ {\vphantom {p \pi }} \right. \kern-0em} \pi }\) ) are interpreted in terms of radially expanding thermalized systems and the recombination model.
