摘要
考虑到真空效应 ,用有效拉氏量方法给出了介质对ρ介子质量的影响 ,发现ρ介子质量随温度和化学势的升高而降低 .然后用所得到的结果检验了Brown
We studied the medium effects on ρ meson mass by taking account of the vacuum effects with the effective Lagrangian approach. We show that the ρ meson mass decreases with both temperature and chemical potential. Then we checked the validity of Brown Rho scaling law in different conditions.
