Description
We study the production of mesons in nucleon-nucleon
reactions at center-of-mass momenta of a few GeV using an $N_f=2$
linear sigma model, extended by including the $N_f=2$ multiplets
of (pseudo-) scalar and (axial-) vector mesons and a doublet of
the nucleon together with its chiral partner (the $N^*(1535)$ or
$N^*(1650)$ resonance).
Cross sections for the production of $\pi-$, $\eta-$, $\rho-$ and
$\omega-$mesons will be presented. The results are compared to
experimental data.
