MHV拉格朗日顶点和Parke-Taylor公式

The MHV lagrangian vertices and the Parke-Taylor formula

Chih-Hao Fu

摘要:

我们明确计算的MHV规则拉格朗日在4维的顶点。这证明了由光锥杨-米尔斯理论的正则变换得到的拉格朗日量的顶点与帕克-泰勒公式的所有阶数一致,填补了CSW规则的拉格朗日推导中最初留下的空白。

英文摘要:

We explicitly calculate the vertices of the MHV-rules lagrangian in 4-dimensions. This proves that the vertices in the lagrangian obtained by a canonical transformation from light-cone Yang-Mills theory coincide to all order with the Parke-Taylor formula, filling the gap originally left in the lagrangian derivation of the CSW rules.
