光锥规范中MHV超顶点的生成

Generating MHV super-vertices in light-cone gauge

Chih-Hao Fu

摘要:

本文用手征超场代替标准的矢量超场方法,构造了光锥规范场中的$\mathcal{N}=1$ SYM拉格朗日量,并导出了MHV拉格朗日量。利用手征超场的正则变换条件,总结了规范场和高吉诺场的正则变换。我们证明了$\mathcal{N}=1$ MHV超顶点可以用类似于$\mathcal{N}=4$ MHV超振幅的公式来描述。在讨论中,我们简要地评论了如何从光锥拉格朗日量直接导出$\mathcal{N}=4$ SYM理论的Nair公式。

英文摘要:

We constructe the $\mathcal{N}=1$ SYM lagrangian in light-cone gauge using chiral superfields instead of the standard vector superfield approach and derive the MHV lagrangian. The canonical transformations of the gauge field and gaugino fields are summarised by the transformation condition of chiral superfields. We show that $\mathcal{N}=1$ MHV super-vertices can be described by a formula similar to that of the $\mathcal{N}=4$ MHV super-amplitude. In the discussions we briefly remark on how to derive Nair's formula for $\mathcal{N}=4$ SYM theory directly from light-cone lagrangian.
