BRS symmetry from renormalization group flow
arXiv:hep-th/9412195 · doi:10.1016/0370-2693(94)01676-4
Abstract
By using the exact renormalization group formulation we prove perturbatively the Slavnov-Taylor (ST) identities in SU(2) Yang-Mills theory. This results from two properties: {\it locality}, i.e. the ST identities are valid if their local part is valid; {\it solvability}, i.e. the local part of ST identities is valid if the couplings of the effective action with non-negative dimensions are properly chosen.
