标题： Three -Pion Correlations

摘要： 首先，我们提及在RHIC上对第三阶BEC（玻色-爱因斯坦关联）的经验分析情况。 其次，我们介绍几种理论公式/方法。 第三，我们展示了STAR合作组对130 GeV下Au+Au数据的分析以及PHENIX合作组对200 GeV下Au+Au的初步数据分析。 我们的结果还包括通过核心-晕模型进行的分析。 最后，我们估计在130 GeV下Au + Au碰撞中的相互作用体积为500 fm^3，这与ALICE合作组在2.76 TeV下Pb + Pb碰撞中的V = R_{长} R_{输出} R_{边} \sim 300 fm^3进行了比较。 此外，对RHIC和LHC能量下(2\pi ^+)\pi ^-和(2\pi ^-)\pi ^+组合的实证分析的有用性进行了说明。 显示英文摘要

摘要： First of all, we mention the situation of empirical analyses on 3rd order BEC (Bose-Einstein Correlation) at RHIC. Second, we introduce several theoretical formulae / approaches. Third we present our analyses of data in Au+Au at 130 GeV by STAR and preliminary data in Au+Au at 200 GeV by PHENIX Collaborations. Our results also contain analyses by means of core-halo model. Finally, we estimate that the volume of interaction in Au + Au collisions at 130 GeV is 500 fm^3, which is compared with V = R_{long} R_{out} R_{side} \sim 300 fm^3 in Pb + Pb collision at 2.76 TeV by ALICE Collaboration. Moreover, usefullness of empirical analyses on (2\pi^+)\pi^- and (2\pi^-)\pi^+ combinations at RHIC and LHC energies is remarked.
