NNLO再加载时e+ e-> 3喷流的红外结构

The infrared structure of e+ e- --> 3 jets at NNLO reloaded

Stefan Weinzierl

摘要:

本文用微扰论的方法,详细地讨论了次次领先级e+ e → 3喷注过程的红外奇异性结构。特别强调的是把与软胶子奇异。奇异性结构的知识允许适当的减法项的建设,这反过来又可以实现到一个数值蒙特卡罗程序。

英文摘要:

This paper gives detailed information on the structure of the infrared singularities for the process e+ e- --> 3 jets at next-to-next-to-leading order in perturbation theory. Particular emphasis is put on singularities associated to soft gluons. The knowledge of the singularity structure allows the construction of appropriate subtraction terms, which in turn can be implemented into a numerical Monte Carlo program.
