软共线规范玻色子的红外发散

Infrared Divergences from Soft and Collinear Gauge Bosons

Paul Jameson

摘要:

我回顾李Nauenberg定理,并讨论其包含的光子是断开的S-矩阵的水平,但连接在横截面的水平时,有初态和终态带电粒子。然后,我揭露了一组新的软共线发散在无质量的规范理论,这是省略了标准的李Nauenberg方法。看来,要得到有限的横截面,需要有一些很有问题的假设。

英文摘要:

I review the Lee-Nauenberg thereom and discuss its inclusion of photons which are disconnected at the level of the S-matrix but connected at the level of the cross-section when there are initial and final state charged particles. I then expose a new set of soft collinear divergences in massless gauge theories which are omitted in the standard Lee-Nauenberg approach. It seems that highly questionable assumptions are needed to obtain finite cross-sections.
