In this paper, we evaluate the self-energy of the vector mesons at one loop in our recently proposed subtraction scheme for the massive nonlinearly realized SU(2) Yang-Mills theory. We check the fulfillment of physical unitarity. The resulting self-mass can be compared with the value obtained in the massive Yang-Mills theory based on the Higgs mechanism, consisting in extra terms due to the presence of the Higgs boson (tadpoles included). Moreover, we evaluate all the one-loop counterterms…

It is shown that all the divergences of the one-particle irreducible (1-PI) amplitudes can be classified according to the solutions of the LFE, and applications to the non-linearly realized Yang-Mills theory and the electroweak theory are briefly addressed.
