论文摘要
由最近对正包含喷气生产的实验性LHC测量以及基于我们先前对前向Hadron Productions的计算的计算，我们计算出颜色玻璃冷凝物框架内的往前快速碰撞的单个包含喷气式横截面，直到近代领先地。此外，随着射流算法的应用以及速度和共线发散的适当减法，我们进一步证明了由此产生的近代领导级硬系数是有限的。此外，为了处理可能破坏扰动扩展的收敛性并提高数值预测的可靠性的大对数，我们引入了共线射流函数和阈值射流函数，并恢复这些隐藏在硬系数中的大对数。
Motivated by recent experimental LHC measurements on the forward inclusive jet productions and based on our previous calculations on forward hadron productions, we calculate single inclusive jet cross-section in $pA$ collisions at forward rapidity within the color glass condensate framework up to the next-to-leading-order. Moreover, with the application of jet algorithm and proper subtraction of the rapidity and collinear divergences, we further demonstrate that the resulting next-to-leading-order hard coefficients are finite. In addition, in order to deal with the large logarithms that can potentially spoil the convergence of the perturbative expansion and improve the reliability of the numerical predictions, we introduce the collinear jet function and the threshold jet function and resum these large logarithms hidden in the hard coefficients.
