关于前向pA碰撞的阈值恢复

On the Threshold Resummation in Forward pA Collisions

Bo-Wen Xiao, Feng Yuan

摘要:

本文以质子-核碰撞中前向快度区的Higgs粒子产生为例,证明了在饱和形式下,我们可以建立一个系统的前向快度粒子产生阈值的形式。将满足相应重整化群方程的前向阈值喷流函数引入到新的因式分解公式中。该计算结果可以推广到其它过程,如前向快度区的单个前向强子产生,并具有重要的唯象意义。

英文摘要:

In this paper, using the Higgs production in forward rapidity region in proton-nucleus collisions as an example, we demonstrate that we can construct a systematic formalism for the threshold resummation for forward rapidity particle productions in the saturation formalism. The forward threshold jet function, which satisfies the corresponding renormalization group equation, is introduced into the new factorization formula. This calculation can be easily generalized to other processes, such as single forward hadron productions at forward rapidity region, and have important phenomenological implications.
