Tim R. Morris, Zhiguang Xiao
TL;DR
This paper explores the relationship between massive CSW vertices and quark vertices in SQCD using a light-cone SUSY transformation, and derives the MHV-SQCD Lagrangian through canonical transformations.
Contribution
It introduces a light-cone SUSY transformation to relate massive CSW vertices and derives the MHV-SQCD Lagrangian from canonical transformations.
Findings
Massive CSW vertices for SQCD can be derived using the proposed SUSY transformation.
The MHV-SQCD Lagrangian can be fixed by applying the transformation to known MHV-QCD transformations.
The approach unifies the understanding of massive vertices in SQCD.
Abstract
The similarity of massive CSW scalar vertices and quark vertices can be understood using a kind of light-cone SUSY transformation presented in this paper. We also show that the canonical transformation generating the MHV-SQCD lagrangian, can be fixed by applying this light-cone SUSY transformation to the canonical transformation for MHV-QCD obtained in paper arxiv:0805.0239. Most of the massive CSW vertices for SQCD can also be pinned down in this way.
