The ward identities of the gauge invariant three boson vertices
Kostas Philippides · AIP conference proceedings · 1995
We outline the pinch techniques for constructing gauge invariant Green’s functions in gauge theories and derive the Ward identities that must be satisfied by the gauge invariant three boson vertices of the standard model. They are generalizations of their tree level Ward identities and are shown to be crucial for the delicate gauge cancellations of the S‐matrix.
