Abstract
The propagation of the scalar (Ï and δ) and vector (Ï and Ï) mesons in an iso-asymmetric nuclear matter is studied in detail, using the Walecka model. We calculate the invariant masses and spectral functions of the mesons, including the effect of meson mixing. At finite density, the mixing effect is quite important in the propagation of the scalar and (longitudinal) vector mesons. In the Ï channel, we find a three-peak structure in the spectral function, caused by the mixing effect.
