Energy and System Size Dependence of Strangeness Production from SPS to RHIC

Abstract

Strange particle production is an important experimental observable that allows the study of the strongly interacting matter created in relativistic heavy-ion collisions. The STAR experiment at RHIC has a unique capability of measuring identified strange particles over a wide range of acceptance providing a rich set of data to perform a systematic study. In addition to the data from Au+Au collisions, strange particles from p+p and d+Au collisions are also available for comparison and normalization. A new set of data from Cu+Cu reactions at 62 GeV and 200 GeV provides the chance to compare the system size dependence observed in Au+Au collisions with this smaller system size. In addition to the comparison of the yields, a statistical thermal model was used to extract freeze-out characteristics for the different system sizes and collision energies.
