Light meson production in nucleon-nucleon reactions — •Khaled Teilab, Susanna Gallas, Francesco Giacosa, and Dirk H. Rischke — Goethe-Universität, Frankfurt

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 π−, η−, ρ− and ω−mesons will be presented. The results are compared to experimental data.
