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

摘要： 我们报告了在STAR实验中，最中心（0-5%）的Au+Au碰撞下，在中 rapidity（|y|<0.5）处Ks、Lambda和Xi谱的测量结果，碰撞能量为\sqrt{s_NN}= 7.7、11.5和39 GeV。提取的产率以及由NA49和CERES实验在SPS测得的Pb+Pb碰撞对应数据是一致的。在所有三个能量下，Lambda、反Lambda、Xi-和Xi+与π介子的比值与统计强子化模型的预测相符。 显示英文摘要

摘要： 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.
