Consistency Condition for the Pinch Technique Self-Energies at Two Loops
Kostas Philippides, Alberto Sirlin
Abstract
A simple and testable necessary condition for the gauge independence of the Pinch Technique self-energies at two loops is discussed. It is then shown that, in the case of the Z and W self-energies, the condition is indeed satisfied by the Papavassiliou-Pilaftsis formulation.
