报告摘要：For a massive gauge theory on a physical gauge, the longitudinal polarization can be naturally identified to be the mixture of the goldstone mode and a remnant gauge component. I propose reorganising Feynman rules by treating gauge fields and goldstone fields uniformly as 5-component vector fields. The results show many simplifications for the Feynman rules and calculations. I also discuss possible applications of our methods on numerical calculations software, such as Madgraph; on-shell approach to scattering amplitudes; SMEFT and Higgs precision measurements and etc.
