Abstract:

QCD as the theory of quarks and gluons is the underlying theory of the hadronic world. However, QCD is not analytically solvable in the low and intermediate energy regimes. While chiral perturbation theories can be applied at low energies, for intermediate energies one needs to use effective models.
In my talk I will present an effective model of QCD (the so-called extended linear sigma model ) which includes (pseudo-)scalar and (axial-)vector mesons as well as spin 1/2 baryons. The model implements two important symmetries of QCD, namely the chiral symmetry and dilatation symmetry together with their spontaneous and explicit breaking. The extended linear sigma model turns out to be very successful in describing the mass and decay widths of the included mesons up to N_f=4 and was also successfully applied to study scattering processes of baryons.
I will highlight the main results of the model and discuss planned future extensions and studies which can be measured experimentally.
