Ye Li, Hua Xing Zhu

摘要:

利用Bootstrap技术和超对称分解,计算了强子对撞机上Drell-Yan或Higgs产生的横动量重算的软函数,并将其推广到强耦合展开的三个循环.提取了相应的快度反常维数。一个有趣的关系异常尺寸的横动量重和阈值重被发现。

英文摘要:

Soft function relevant for transverse-momentum resummation for Drell-Yan or Higgs production at hadron colliders are computed through to three loops in the expansion of strong coupling, with the help of bootstrap technique and supersymmetric decomposition. The corresponding rapidity anomalous dimension is extracted. An intriguing relation between anomalous dimensions for transverse-momentum resummation and threshold resummation is found.
