Scaling effective Lagrangians in a dense medium
Abstract
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/mσ~=m*N/mN ~=m*ρ/mρ~=m*ω/mω~=f*π/fπ. This has a highly nontrivial implication for nuclear processes at and above nuclear-matter density. Some concrete cases are cited in this paper.
