Scaling effective Lagrangians in a dense medium

By using effective chiral Lagrangians with a suitable incorporation of the scaling property of QCD, we establish the approximate in-medium scaling law, m_σ*/m_σ{}mN*/mN {}m_ρ*/m_ρ{}m_ω*/m_ω{}f_π*/f_π. This has a highly nontrivial implication for nuclear processes at and above nuclear-matter density. Some concrete cases are cited in this paper.
