论文摘要
我们在n $^3 $ ll+nnlo准确度上为$ q_t $重新召集的框架，以基于cot中的分解定理进行任意色彩单词过程。我们的实现可爱的MCFM在天生的运动学中完全差异，并且在相对顺序$α_s^2 $的情况下与$ Q_T $ Q_T $固定订单预测相匹配。它提供了一种有效的方法来估计固定顺序截断，重新召集和Parton分布功能的不确定性。除了$ w^\ pm $，$ z $和$ h $生产外，还提供diboson流程$γγ，zγ，zh $和$ w^\ pm h $，包括衰变。我们通过与实验测量以及包容性基准结果进行了几次直接比较来讨论和举例说明框架。特别是，我们提出了$γγ$和$zγ$的新颖结果，n $^3 $ ll+nnlo详细讨论了光子隔离要求引起的功率校正。
We present a framework for $q_T$ resummation at N$^3$LL+NNLO accuracy for arbitrary color-singlet processes based on a factorization theorem in SCET. Our implementation CuTe-MCFM is fully differential in the Born kinematics and matches to large-$q_T$ fixed-order predictions at relative order $α_s^2$. It provides an efficient way to estimate uncertainties from fixed-order truncation, resummation, and parton distribution functions. In addition to $W^\pm$, $Z$ and $H$ production, also the diboson processes $γγ,Zγ,ZH$ and $W^\pm H$ are available, including decays. We discuss and exemplify the framework with several direct comparisons to experimental measurements as well as inclusive benchmark results. In particular, we present novel results for $γγ$ and $Zγ$ at N$^3$LL+NNLO and discuss in detail the power corrections induced by photon isolation requirements.
