在RHIC的e + e对产生中高阶QED的证据

Evidence for higher order QED in e+ e- pair production at RHIC

A. J. Baltz

摘要:

对在STAR ZDC触发器中观测到的重离子核库仑离解进行唯象处理,对RHIC e~+ e~-对产生进行了一种新的最低阶QED计算。最低阶QED结果的实验可接受性比STAR数据大近两个标准差。相应的高阶QED计算结果与实验数据一致。

英文摘要:

A new lowest order QED calculation for RHIC e+ e- pair production has been carried out with a phenomenological treatment of the Coulomb dissociation of the heavy ion nuclei observed in the STAR ZDC triggers. The lowest order QED result for the experimental acceptance is nearly two standard deviations larger than the STAR data. A corresponding higher order QED calculation is consistent with the data.
