    • It predicts, in a medium, mNstar/ mσstar= 3 / 2 for all density and hence mσstar/ mσ= mNstar/ mN. However, since the cutoff mass used in the model is comparable to vector-meson masses, it is difficult to trust its prediction of the in-medium behavior of the vector mesons.

    • The scale invariance of this term explains why the Skyrme Lagrangian gives, in the high-density limit, the same asymptotic property as noninteracting quarks.

    • This together with Eq. (21) gives [ ( gstar/ mVstar) / ( g / mV) ]2 approx ( fπstar/ fπ)-2approx ( mNstar/ mN)-2 as suggested by G. E. Brown and M. Rho [, ] to argue for the disappearance of tensor forces in nuclear matter.

    • Up to ρ = ρ0, the nucleon radius is roughly constant because of the interplay between the factor gAstar/ gA which decreases and fπ/ fπstar which increases. This effect is important for y scaling in nuclei as shown in Ref. 13.
