Abstract
We present the results of meson time-like modes in a dense baryonic me dium. The model used is the Nambu-Jona-Lasinio model extended to inclu de vector mesons. We find results for the pi-, sigma-, omega- and a1-m eson time-like modes. We use the same extrapolation technique we have already used to avoid the impossibility of putting heavy mesons on-she ll. Vector-meson modes split into a longitudinal and a transverse mode . The sigma-mode mixes with the longitudinal omega-mode.
