An extended linear sigma model with mesons (q\bar{q} states) and baryons (qqqstates) is presented. The model contains a low energy multiplet for everyhadronic particle type, namely a scalar, a pseudoscalar, a vector, and anaxialvector nonet, an baryon octet and a baryon decuplet. The model parametersare determined through a multiparametric minimalization with the help of wellknown physical quantities. It is found that the considered zero temperaturequantities (masses and decay widths) can be described well at tree-level andare in good agreement with the experimental data.
