Abstract:

We derive the Landau-Migdal parameters g'N for nucleon particle-hole states, g'Δ for nucleon and delta particle-hole states and g'ΔΔ for delta particle-hole states within the π+ρ model. Then density as well as the momentum dependences of these parameters are studied. The three parameters turn out to be about 0.6 - 0.65 in pion mass unit at zero momentum, once the contributions from other channels, especially the non-spin non-isospin channel, and those from the induced interactions are included.
