Two-loop electroweak corrections to the parameter beyond the leading approximation
Joannis Papavassiliou, Kostas Philippides, Ken Sasaki
We show that in the framework of the pinch technique the universal part of the parameter can be meaningfully defined, beyond one loop. The universal part so obtained satisfies…

A Gauge-Independent Approach to Resonant Transition Amplitudes
Joannis Papavassiliou, Apostolos Pilaftsis
We present a new gauge-independent approach to resonant transition amplitudes with nonconserved external currents, based on the pinch technique method. In the context of a…
