论文摘要
长期以来,浓的味道一直被认为是在高能核碰撞中产生的夸克gluon等离子体的探测。在本文中,我们回顾了极端条件下的重风味和重离子实验中的实现。在简短地介绍了真空中的重风味特性之后,我们强调了对重型风味的冷和热核物质的影响,包括阴影效应,cronin效应和前者的核吸收以及后者的Debye筛选和再生。然后,我们在运输和合并模型的框架中讨论了这些介质引起的核碰撞中开放和封闭的重型风味的变化,并与核子核子碰撞进行了比较。考虑到非中心核碰撞中产生的极强电磁和旋转场,近年来对此进行了广泛研究,我们最终研究了它们对高能核碰撞中重型风味产生和进化的影响。
Heavy flavor hadrons have long been considered as a probe of the quark gluon plasma created in high energy nuclear collisions. In this paper we review the heavy flavor properties under extreme conditions and the realization in heavy ion experiments. After a short introduction on heavy flavor properties in vacuum, we emphasize the cold and hot nuclear matter effects on heavy flavors, including shadowing effect, Cronin effect and nuclear absorption for the former and Debye screening and regeneration for the latter. Then we discuss, in the frame of transport and coalescence models, these medium induced changes in open and closed heavy flavors in nuclear collisions and the comparison with nucleon-nucleon collisions. Considering the extremely strong electromagnetic and rotational fields generated in non-central nuclear collisions, which are widely studied in recent years, we finally investigate their effects on heavy flavor production and evolution in high energy nuclear collisions.
