论文摘要
我们开发一个分解框架，以计算软滴式喷气质量和修饰喷射半径的双差分横截面。我们描述了由射流质量相互作用和修饰的射流半径测量所定义的大型，中间和小的射流半径区域中的有效理论。作为一个应用程序，我们介绍了与系数$ c_1 $和$ c_2 $相关的扰动矩的NLL $'$结果，该系数指定了高达三个通用参数的领先强调校正。我们将结果与蒙特卡洛模拟和使用相干分支方法进行计算进行了比较。
We develop a factorization framework to compute the double differential cross section in soft drop groomed jet mass and groomed jet radius. We describe the effective theories in the large, intermediate, and small groomed jet radius regions defined by the interplay of the jet mass and the groomed jet radius measurement. As an application we present the NLL$'$ results for the perturbative moments that are related to the coefficients $C_1$ and $C_2$ that specify the leading hadronization corrections up to three universal parameters. We compare our results with Monte Carlo simulations and a calculation using the coherent branching method.
