重离子碰撞中的双轻子探测

The dilepton probe in heavy-ion collisions

H. van Hees

摘要:

双轻子提供了在重离子碰撞中形成的热的和/或稠密的介质中的电磁电流-电流相关器的直接可观测量。本文从多体理论中强子和部分子在介质中性质的研究以及与手征相变基本问题的联系出发,综述了重离子碰撞中双轻子现象的理论认识现状。

英文摘要:

Dileptons provide direct observables of the electromagnetic current-current correlator in the hot and/or dense medium formed in heavy-ion collisions. In this article an overview is given about the status of the theoretical understanding of the dilepton phenomenology in heavy-ion collisions from studies of the in-medium properties of hadrons and partons within many-body theory and about connections to fundamental questions concerning the chiral phase transition.
