高能重离子碰撞中喷注的光生过程

The photoproduction processes for jet in the high energy heavy ion collisions

简要综述了高能重离子碰撞中的光生过程,并简要讨论了喷注的光生机制.在高能重离子碰撞中,当转移动量很小时,该过程就是准实光子与核子(或部分子)的相互作用过程,即高能重离子碰撞中所谓的光生过程.

In the paper, we review the photoproduction processes in the high energy heavy-ion collisions, and we also discuss the jet photoproduction mechanism. When the transverse momentum is very small, the high energy heavy-ion collisions can be treated as the processes that the quasi real photon interacts with the nucleon（or parton）, this is so-called the photoproduction processes in the high energy heavy-ion collisions.
