The dual gauge fixing property of the S matrix
Joannis Papavassiliou, Kostas Philippides
The -matrix is known to be independent of the gauge fixing parameter to all orders in perturbation theory. In this paper by employing the pinch technique we prove at one loop a…
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…
LEADING VACUUM-POLARIZATION CONTRIBUTIONS TO THE RELATION BETWEEN POLE AND RUNNING MASSES
K. Philippides, A. Sirlin
The vacuum--polarization contributions of ${\cal O}(b^{n-1} \al_s^n)$ to the relation between the pole--mass of a quark and the \MS parameter $\mh (M)$ are evaluated by a strai…
The heavy quark decomposition of the S-matrix and its relation to the pinch technique
Joannis Papavassiliou, Kostas Philippides, Martin Schaden
We propose a decomposition of the S-matrix into individually gauge invariant sub-amplitudes, which are kinematically akin to propagators, vertices, boxes, etc. This decompsition is…
