Implementation of non-linear gauge-fixing in FeynArts package
Feynman rules for the Standard Model including non-linear gauges are derived and implemented in the FeynArts package. The calculations using FeynArts with the new rules show that tree-level amplitudes are gauge invariant and that renormalization is not spoiled for one-loop calculations. The FeynArts...

| Zusammenfassung: | Feynman rules for the Standard Model including non-linear gauges are derived
and implemented in the FeynArts package. The calculations using FeynArts with
the new rules show that tree-level amplitudes are gauge invariant and that
renormalization is not spoiled for one-loop calculations. The FeynArts model
