摘要:

我们提出了一个全球性的分析,包括最新的数据从合并HERA分析减少截面的电子-质子散射在小值的Bjorken-x测量的包容性结构功能的可用数据。我们的方法依赖于偶极制定DIS一起使用的非线性运行耦合BK方程的描述的小x动力学。通过由此产生的参数化,我们能够描述H1合作测量的最新FL数据。此外,我们还讨论了运动学域的显着偏离NLO-DGSTARY应预期和能力的非linnear物理来解释这种偏差。

英文摘要:

We present a global analysis of available data on inclusive structure functions measured in electron-proton scattering at small values of Bjorken-x, including the latest data from the combined HERA analysis on reduced cross sections. Our approach relies on the dipole formulation of DIS together with the use of the non-linear running coupling BK equation for the description of the small-x dynamics. With the resulting parametrization we are able to describe the latest FL data measured by the H1 collaboration. Further, we discuss the kinematical domain where significant deviations from NLO-DGLAP should be expected and the ability of non-linnear physics to account for such deviations.
