Abstract
We study the all-order restoration of the Slavnov-Taylor (ST) identities for Yang-Mills theory with massive fermions in the presence of singlet axial-vector currents. By making use of the ST parameterization of the symmetric quantum effective action a natural set of normalization conditions is derived allowing to reduce the algebraic complexity of higher orders ST identities up to a homogeneous linear problem. Explicit formulas for the action-like part of the symmetric vertex functional are given to all orders in the loop expansion.Pubblicazioni consigliate
