Abstract
The so-called extended linear sigma model is a chiral model with (pseudo)scalar and (axial-)vector mesons. It is based on the requirements of (global) chiral symmetry and dilatation invariance. The purpose of this model is the description of the hadron phenomenology up to 1.7 GeV. We present the latest theoretical results, which show a good agreement with the experiment.

In this paper we describe a chiral σ model, called ‘extended Linear σ model (Elσm)’, in which scalar, pseudoscalar, vector, axial-vector quark-antiquark mesons and,in addition, a scalar dilaton/glueball field are the basic degrees of freedom
