In quantum field theory, characteristics of resonances are related to self-energy diagrams, which are ultra-violet divergent and require renormalization. We demonstrate the proper way to define the resonance coupling gM such that the resonance properties calculated in quantum field theory are finite and scheme-independent quantities.
