Measurements of Ks, Lambda and Xi from Au+Au collisions at \sqrt{s_NN} = 7.7, 11.5 and 39 GeV in STAR

Abstract

We report on the measurements of Ks, Lambda and Xi spectra at mid-rapidity (|y|<0.5) in the most central (0-5%) Au+Au collisions at \sqrt{s_NN} = 7.7, 11.5 and 39 GeV from the STAR experiment. The extracted yields and the corresponding data from Pb+Pb collisions measured by the NA49 and CERES experiments at SPS are consistent. The Lambda, Anti-Lambda, Xi- and Xi+ to pion ratios agree well with the predictions from a statistical hadronization model at all three energies.
