Query: Phenomenology of light mesons within a chiral approach   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.
