FEYNMAN-RULES AND BETA-FUNCTION FOR THE BF YANG-MILLS THEORY

Yang-Mills theory in the first order formalism appears as the deformat ion of a topological field theory, the pure BF theory, We discuss this formulation at the quantum level, giving the Feynman rules of the BF- YM theory, the structure of the renormalization and checking its uv-be haviour in the computation of the beta-function which agrees with the expected result.
