Abstract

Description

We calculate the effective mass m_ω^* of the ω-meson in nuclear medium by the σ-ωmodel with a vector field self-interaction (VFSI). We found that the direct and the indirect effects of the VFSI almost cancel each other and the result is changed only slightly at the normal density. The VFSI makes m^*_ωsmaller at lower density and makes m_ω^* larger at higher density. However, both effects are not large.
