H. Fujii, K. Itakura, Y. Kitadono, Y. Nara

摘要:

为了描述高能核碰撞中的前向强子产生,我们提出了Dumitru-Hayashigaki-Jalilian-Marian公式的Monte-Carlo实现,该公式采用了由运行耦合BK方程数值计算得到的未积分胶子分布.我们讨论了BK方程的初始条件的影响,通过比较小x HERA数据的全局拟合约束的模型和一个新提出的运行耦合MV模型。

英文摘要:

In order to describe forward hadron productions in high-energy nuclear collisions, we propose a Monte-Carlo implementation of Dumitru-Hayashigaki-Jalilian-Marian formula with the unintegrated gluon distribution obtained numerically from the running-coupling BK equation. We discuss influence of initial conditions for the BK equation by comparing a model constrained by global fit of small-x HERA data and a newly proposed one from the running coupling MV model.
