标题： Evolution of event-by-event transverse-energy fluctuations over collision centrality in RHIC interactions

摘要： 初步结果介绍了对横能（ET）产生的两种分析，这些分析是通过Pioneering High Energy Nuclear Interaction Experiment（PHENIX）的电磁量能器测量的，在相对论重离子碰撞机（RHIC）在布鲁克海文国家实验室创建的Au+Au重离子碰撞中的核相互作用中进行的。 按碰撞中心性跨事件的ET分布用于（1）200 GeV平均ET的测量，以及（2）200 GeV和62.4 GeV ET分布波动的测量。 事件中心性选择在5%宽的区间内，每个区间由模拟的参与核子的平均数表示。 显示英文摘要

摘要： Preliminary results are presented for two analyses of transverse energy (ET) production measured with the electromagnetic calorimeters of the Pioneering High Energy Nuclear Interaction Experiment (PHENIX), in nuclear interactions in Au+Au heavy-ion collisions created by the Relativistic Heavy Ion Collider (RHIC), at Brookhaven National Laboratory. Event-by-event ET distributions made across collision centrality were used in (1) measurements of 200 GeV mean ET, and (2) measurements of 200 GeV and 62.4 GeV ET distribution fluctuations. Event centrality was selected in 5% wide bins and each bin represented by a modeled mean number of participant nucleons.
