Renormalization of the antisymmetric tensor field propagator and dynamical generation of the 1+ − mesons in Resonance Chiral Theory

We discuss the renormalization of the 1−− vector meson propagator within Resonance chiral theory at one loop. Using the particular form of the interaction Lagrangian we show that additional poles of the renormalized propagator corresponding to 1+ − degrees of freedom can be generated. We give a concrete example of such an effect.
