Abstract
Based on the thermo field dynamics, the temperature-and density-depend ent effective mass and screening mass of rho meson in the vector-tense r rho-meson-nucleon-nucleon coupling model have been calculated. The e ffects of the vacuum fluctuation corrections through the effective nuc leon mass are examined. We have shown that the vacuum fluctuation give s an important correction to the self-energy of rho meson and leads to a reduction of p-meson mass in hot and dense matter.
