CSW rules for massive matter legs and glue loops
Rutger Boels, Christian Schwinn
Cachazo-Svrcek-Witten-type Feynman rules for massive matter scalar legs and pure glue loops are presented, obtained by deriving them directly from the space-time action. We comment…
Recent developments for multi-leg QCD amplitudes with massive particles
Rutger Boels, Christian Schwinn, Stefan Weinzierl
We review the extension of modern techniques for the calculation of helicity amplitudes in QCD to massive particles. The focus is on the use of supersymmetric Ward identites that r…
CSW rules for a massive scalar
Rutger Boels, Christian Schwinn
We derive the analog of the Cachazo-Svrcek-Witten (CSW) diagrammatic Feynman rules for four dimensional Yang-Mills gauge theory coupled to a massive colored scalar. The mass term i…
A quantization of twistor Yang-Mills theory through the background field method
Rutger Boels
Four dimensional Yang-Mills theory formulated through an action on twistor space has a larger gauge symmetry than the usual formulation, which in previous work was shown to allow a…
From Twistor Actions to MHV Diagrams
Rutger Boels, Lionel Mason, David Skinner
We show that MHV diagrams are the Feynman diagrams of certain twistor actions for gauge theories in an axial gauge. The gauge symmetry of the twistor action is larger than that on…
