Measurements of Strangeness Production on Au+Au collisions at 62 GeV

Abstract

The STAR (Solenoidal Tracker at RHIC) experiment is a large acceptance collider detector that measures primarily hadronic observables to search for signatures of the quark‐gluon plasma phase transition and study strongly interacting matter at high energy density. Operational since June 2000, the new heavy ion collider RHIC has already provided Au+Au collisions at σNN = 62, 130 and 200 GeV as well as p+p and d+Au collisions at 200 GeV. The various collision energies and systems allow the systematic study of particle production in heavy ion collisions. In particular, the production of strange (anti‐)particles is one of the major topics of STAR. This detector allows the measurement of a variety of particle species at mid‐rapidity, like neutral kaons; Λ, Ⅺ, and Ω. hyperons; and their anti‐particles that are reconstructed via their decay topology. The strangeness measurements should provide important information on various phenomenological aspects of ultra‐relativistic heavy ion collisions. The goal of this wo...
