Abstract

Based on the thermo field dynamics, the temperature-and density-dependent effective mass and screening mass of rho meson in the vector-tenser rho-meson-nucleon-nucleon coupling model have been calculated. The effects of the vacuum fluctuation corrections through the effective nucleon mass are examined. We have shown that the vacuum fluctuation gives an important correction to the self-energy of rho meson and leads to a reduction of p-meson mass in hot and dense matter.
