P. Phukan, M. Lalung, J. K. Sarma

摘要:

利用Mellin变换和鞍点近似,给出了Balitsky-Kovchegov方程的精确解析解.这种解决方案的理论意义是它的形式简单,需要很少的参数。利用这个解和彩色玻璃凝聚体的思想,我们得到了d-Au,p-p和p-Pb碰撞的RHIC和LHC微分产额数据的一个很好的描述。给出了与最近LHC运行2有关的p-Pb、Pb-Pb和Xe-Xe碰撞的核修正因子的定量预测。

英文摘要:

An exact analytical solution to the Balitsky-Kovchegov equation is proposed incorporating Mellin transformation with saddle point approximation. The theoretical significance of this solution is its simplicity in form which requires very less number of parameters. Using this solution along with the idea of color glass condensate, a very good description of RHIC and LHC data on differential yield is obtained for d-Au, p-p and p-Pb collisions. Quantitative prediction for the nuclear modification factors for p-Pb, Pb-Pb and Xe-Xe collisions relevant for very recent LHC run 2 is yielded.
