Abstract
The properties ofρ-mesons in dense nuclear matter are studied in a model which satisfies unitarity and current conservation. The important coupling of theρ-meson to two pions as well as the strong mixing of pions and delta-nucleon-hole states in nuclear matter are included. Theρ-meson self energy in nuclear matter is evaluated with in-medium pion propagators and the corresponding vertex corrections required by current conservation. We find that theρ-meson width grows drastically with increasing density while its mass remains almost unchanged.
