论文摘要
我们讨论了对电子脉络膜歼灭中HADRONIC最终状态的修饰事件形状重新介绍的重新介绍的状态。 We identify the missing ingredients needed for next-to-next-to-next-to-leading logarithmic (NNNLL) resummation of the mMDT groomed jet mass in $e^+e^-$ collisions: the low-scale collinear-soft constants at two-loop accuracy, $c_{S_c}^{(2)}$, and the three-loop non-cusp anomalous dimension of the global软功能，$γ_s^{（2）} $。我们提出了一种使用固定顺序代码提取这些常数的方法：Event2程序以获取$ C_ {S_C}^{（2）} $的颜色系数和提取$γ_S^{（2）} $的MCCSM。我们介绍了所有必要的公式，以重新调整MMDT的重型喷气质量分布在NNLLL精度下。
We discuss the status of resummation of large logarithmic contributions to groomed event shapes of hadronic final states in electron-positron annihilation. We identify the missing ingredients needed for next-to-next-to-next-to-leading logarithmic (NNNLL) resummation of the mMDT groomed jet mass in $e^+e^-$ collisions: the low-scale collinear-soft constants at two-loop accuracy, $c_{S_c}^{(2)}$, and the three-loop non-cusp anomalous dimension of the global soft function, $γ_S^{(2)}$. We present a method for extracting those constants using fixed-order codes: the EVENT2 program to obtain the color coefficients of $c_{S_c}^{(2)}$, and MCCSM for extracting $γ_S^{(2)}$. We present all necessary formulae for resummation of the mMDT groomed heavy jet mass distribution at NNNLL accuracy.
