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.
