论文摘要

我们使用彩色玻璃冷凝物形式主义计算出深度非弹性散射(DIS)的单环校正,以小$ x $的深度弹性散射(DIS)计算单层校正。我们表明,根据Jimwlk Evolution方程和Parton-Hadron碎片函数的DGLAP演变,彼此之间的差异(NLO)校正的差异部分相互取消或导致$ x $(速度)的演变。其余有限零件构成了NLO($α_s$)的校正,以小$ x $以DIS为单一的包含强体生产横截面。

We calculate the one-loop corrections to single inclusive hadron production in Deep Inelastic Scattering (DIS) at small $x$ in the forward rapidity region using the Color Glass Condensate formalism. We show that the divergent parts of the next to leading order (NLO) corrections either cancel among each other or lead to $x$ (rapidity) evolution of the leading order (LO) dipole cross section according to the JIMWLK evolution equation and DGLAP evolution of the parton-hadron fragmentation function. The remaining finite parts constitute the NLO ($α_s$) corrections to the LO single inclusive hadron production cross section in DIS at small $x$.
