标题： The Exclusive kT Dijet Rate in SCET with a Rapidity Regulator

摘要： 我们使用有效场论技术研究(kT)独占喷注算法。 在软-胶子有效理论(SCET)中正则化图的虚度和快速度，我们可以将下一阶双喷注截面写成单独硬、喷注和软贡献的乘积。 我们展示如何以前由相干分支形式计算的下一阶对数精度的Sudakov形式因子重现出来。 我们的结果仅依赖于硬函数的重整化群演化，而不是像在SCET中通常那样依赖于硬函数和喷注函数的重整化群演化。 我们指出在这种情况下正则化快速度是不必要的。 显示英文摘要

摘要： We study the (exclusive) kT jet algorithm using effective field theory techniques. Regularizing the virtualities and rapidities of graphs in the soft-collinear effective theory (SCET), we are able to write the next-to-leading-order dijet cross section as the product of separate hard, jet, and soft contributions. We show how to reproduce the Sudakov form factor to next-to-leading logarithmic accuracy previously calculated by the coherent branching formalism. Our result only depends on the renormalization group evolution of the hard function, rather than on that of the hard and jet functions as is usual in SCET. We comment that regularizing rapidities is not necessary in this case.
