Description
In this talk, I present an effective model based on the linear
representation of the chiral U(N_f)_r x U(N_f)_l symmetry of QCD. It is demonstrated that a reasonable fit of the mass parameters and coupling constants of the model to hadron vacuum properties can be obtained. This study can contribute to answering the question about the quark content of the scalar isoscalar mesons. The model is used to investigate dilepton production in NN and AA collisions and to search for signatures of chiral symmetry restoration at nonzero temperatures and densities.
