Abstract
A general analysis of the Slavnov-Taylor identity connecting the triple gluon and ghost-ghost-gluon vertices and its consequences for two momentum subtraction (symmetric and asymmetric) renormalization schemes are given. It is shown that in the asymmetric scheme proposed in this paper the relation \(Z_3 Z_{1^{ - 1} } = \tilde Z_8 \tilde Z_{1^{ - 1} }\)follows directly from the identity for a simple and natural definition of the renormalization constants. Explicit one-loop expressions for the renormalization constants \(\left( {Z_1 ,Z_3 ,\tilde Z_1 \tilde Z_3 } \right)\)in an arbitrary covariant gauge, including quark masses are given in support of the general analysis.
