Nontrivial quadratic gauge-fixing in Yang-Mills theories
We study renormalizability of a quadratic gauge-fixing choice involving gauge fields. We show that this can be renormalized simultaneously maintaining the BRS invariance since this respects the underlying global SU(
n ) invariance. However, this choice, too, induces quartic ghost terms in conformity with our earlier results. -
