Renormalization and additional degrees of freedom within the chiral effective theory for spin-1 resonances
We study in detail various aspects of the renormalization of the spin-1 resonance propagator in the effective field theory framework. First, we briefly review the formalisms for the description of spin-1 resonances in the path integral formulation with the stress on the issue of propagating degrees of freedom. Then we calculate the one-loop 1(--) meson self-energy within the resonance chiral theor
