Production of protons and light nuclei in Au plus Au collisions at √sNN=3 GeV with the STAR detector

Popis výsledku v původním jazyce

We report the systematic measurement of protons and light nuclei production in Au+Au collisions at root s(NN) = 3 GeV by the STAR experiment at the Relativistic Heavy Ion Collider (RHIC). The transverse momentum (p(T)) spectra of protons (p), deuterons (d), tritons (t), He-3, and He-4 have been measured from midrapidity to target rapidity for different collision centralities. We present the rapidity and centrality dependence of particle yields (dN/dy), average transverse momentum (< p(T)>), yield ratios (d/p, t/p, He-3/p, He-4/p), as well as the coalescence parameters (B-2, B-3). The 4 pi yields for various particles are determined by utilizing the measured rapidity distributions, dN/dy. Furthermore, we present the energy, centrality, and rapidity dependence of the compound yield ratios (N-p x N-t/N-d(2)) and compare them with various model calculations. The physics implications of these results on the production mechanism of light nuclei and the QCD phase structure are discussed.
