We present a comprehensive study of mass modifications of scalar,pseudo-scalar, vector, and axial-vector mesons in nuclear matter using thethree-flavor extended Linear Sigma Model (eLSM) and the two-flavor ParityDoublet Model (PDM). The meson masses in nuclear matter are determined bycalculating the one-loop nucleon corrections to the meson mean fields. As aresult, we find all spin-$0$ meson masses except those of the pion, kaon, andthe lightest scalar-isoscalar mesons decrease at finite baryon density. Forspin-$1$ mesons, masses of all axial-vector mesons decrease in medium, and thedensity dependences of the $\rho$ and $\omega$ meson masses strongly depend onthe value of chiral invariant mass ($M_0$). Also, our results suggest$M_0\approx0.8\, {\rm GeV}$ is preferable.
