We study the problems related to the renormalization of propagators in resonance
chiral theory, concentrating on the case of vector resonances in the
antisymmetric tensor formalism. The general form of the propagators for
antisymmetric tensor fields contains not only the resonance states but also the
states that are ghosts or tachyons which decouple in the free-field limit.
However, when the interaction terms are taking into account they are dynamically
generated through the renormalization procedure.
