Lambda(1520) production in d+Au collisions at RHIC

Abstract

Recent results of $\Lambda$(1520) resonance production in d+Au collisions at $\sqrt{s_{\mathrm{NN}}}=$ 200 GeV are presented and discussed in terms of the evolution and freeze-out conditions of a hot and dense fireball medium. Yields and spectra are compared to results from p+p and Au+Au collisions. The $\Lambda$(1520)/$\Lambda$ ratio in d+Au collisions ratio is consistent with the ratio in p+p collisions. This suggests a short time for elastic interactions between chemical and thermal freeze-out. One can conclude that the interaction volume in d+Au collisions is small.
