Strangeness production in √sNN=3 GeV Au+Au collisions at RHIC

Popis výsledku v původním jazyce

We report multi-differential measurements of strange hadron production ranging from mid- to target-rapidity in Au+Au collisions at a center-of-momentum energy per nucleon pair of root sNN = 3 GeV with the STAR experiment at RHIC. K-S(0) meson and Lambda hyperon yields are measured via their weak decay channels. Collision centrality and rapidity dependences of the transverse momentum spectra and particle ratios are presented. Particle mass and centrality dependence of the average transverse momenta of Lambda and K-S(0) are compared with other strange particles, providing evidence of the development of hadronic rescattering in such collisions. The 4 pi yields of each of these strange hadrons show a consistent centrality dependence. Discussions on radial flow, the strange hadron production mechanism, and properties of the medium created in such collisions are presented together with results from hadronic transport and thermal model calculations.
