论文摘要

我们使用完整的近代领导顺序(NLO)影响因子以及改进的Balitsky-Kovchegov进化(包括在低$ x $下的领先对数精度之外的主要效果),使用完整的近代领域影响因子(NLO)影响因子进行了第一台偶极图片拟合。我们发现,最近文献中提出的进化方程的三种不同公式导致对HERA数据的描述非常相似,并对未来的深层非弹性散射实验进行了强大的预测。我们发现表明对光夸克的结构函数的显着非扰动贡献的证据,这强调了将NLO影响因子计算扩展到大量夸克的必要性。

We perform the first dipole picture fit to HERA inclusive cross section data using the full next-to-leading order (NLO) impact factor combined with an improved Balitsky-Kovchegov evolution including the dominant effects beyond leading logarithmic accuracy at low $x$. We find that three different formulations of the evolution equation that have been proposed in the recent literature result in a very similar description of HERA data, and robust predictions for future deep inelastic scattering experiments. We find evidence pointing towards a significant nonperturbative contribution to the structure function for light quarks, which stresses the need to extend the NLO impact factor calculation to massive quarks.
