论文摘要
$ \ hat s/p_t^2 $中的大型对数校正导致大型强子对撞机的包含$ w $ plus-dijet流程的扰动预测发生了很大的变化。可以通过$ \ hat s/p_t^2 $将领先的贡献概括为$α_s$中的所有订单。但是,正如预期的那样,领先的对数准确性不足以保证在远离高能量极限的相位区域中的合适描述。 我们介绍(i)以$ W $ -BOSON生产的近级对数顺序贡献的所有党派通道的第一个计算,并与至少两种喷气机相关,以及(ii)(ii)bin-bin匹配与近代领先的固定订单准确性。这种新的扰动输入是在\ emph {高能喷气机}中实现的,并系统地改善了相对于$ \ hat s/p_t^2 $正式倾斜的相空间区域中可用实验数据的描述。
Large logarithmic corrections in $\hat s/p_t^2$ lead to substantial variations in the perturbative predictions for inclusive $W$-plus-dijet processes at the Large Hadron Collider. This instability can be cured by summing the leading-logarithmic contributions in $\hat s/p_t^2$ to all orders in $α_s$. As expected though, leading logarithmic accuracy is insufficient to guarantee a suitable description in regions of phase space away from the high energy limit. We present (i) the first calculation of all partonic channels contributing at next-to-leading logarithmic order in $W$-boson production in association with at least two jets, and (ii) bin-by-bin matching to next-to-leading fixed-order accuracy. This new perturbative input is implemented in \emph{High Energy Jets}, and systematically improves the description of available experimental data in regions of phase space which are formally subleading with respect to $\hat s/p_t^2$.
