Description

We study two general approaches how to describe spin one particles, using vector and antisymmetric tensor fields within RChT. In this paper we focus on the question of an equivalence of both ways. The appearing problems lead us to the introduction of a new type of the description - the first order formalism which naturally connects both traditional formalisms. Moreover, it gives a more general result on the level of the effective chiral Lagrangian that contain all terms from effective chiral Lagrangians in vector and antisymmetric tensor formulations.
