Model achieves good agreement with experimental data.

Successfully describes meson properties up to 1.7 GeV.

Provides theoretical insights into light meson phenomenology.

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.
