The {ital S} 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 stronger version of this independence. In particular, we show that one can use a gauge-fixing parameter for the gauge bosons inside quantum loops which is different from that used for the bosons outside loops, and the {ital S} matrix is independent of both. Possible phenomenological applications of this result… Expand

TLDR
It is shown how massless Goldstone bosons, not present in the {ital S} matrix, must be introduced into Green's functions in order to reconcile gauge invariance and renormalizability. Expand

TLDR
It is demonstrated that the propagatorlike pinch parts are absorbed in the same self-energies encountered in the four-fermion case, including the possibility of a gauge-invariant on-shell definition of the vector-boson mass. Expand

TLDR
The issue of gauge independence of several quantities in hot QCD is discussed from the pinch technique point of view and it is pointed out that the spurious singularities which appear in TAG calculations cancel out once the pinch contributions are combined. Expand

TLDR
It is shown by explicit calculations that the application of the pinch technique in the framework of the background field method gives rise to exactly the same results as in the linear renormalizable gauges. Expand
