LHeC上eA过程的核纵向结构函数

Nuclear longitudinal structure function in eA processes at the LHeC

G. R. Boroun, B. Rezaei, S. Heidari

摘要:

核子和核的纵向结构函数由低$x$胶子分布的Kharzeev-Levin-Nardin(KLN)模型确定。研究了该过程中胶子分布比$R_{g}={G^{A}}/{AG^{p}}$和$R_{L}^{total}={F_{L}^{A-total}}/{AF_{L}^{p-total}}$的行为,讨论了LHeC区eA过程中的重纵结构函数比.对总纵向结构功能比例的重大贡献是相当大的,不应忽视,尤其是在LHeC项目中较小的$x$中。在KLN模型中,根据LHeC过程,采用了一种新的几何标度来描述从线性区到非线性区的跃迁,其结果强烈依赖于重夸克质量效应。

英文摘要:

The nucleon and nuclear longitudinal structure functions are determined by the Kharzeev-Levin-Nardin (KLN) model of the low $x$ gluon distribution. The behavior of the gluon distribution ratio $R_{g}={G^{A}}/{AG^{p}}$ and the ratio $R_{L}^{total}={F_{L}^{A-total}}/{AF_{L}^{p-total}}$ in this processes are found. The heavy longitudinal structure function ratios in eA processes at the LHeC region are discussed. Heavy contributions to the ratio of the total longitudinal structure function are considerable and should not be neglected especially at smaller $x$ of the LHeC project. In the KLN model the new geometrical scaling for transition from the linear to nonlinear regions in accordance with the LHeC processes is used, whose results intensively depended on the heavy quarks mass effect.
