EFFECTIVE HADRON MASSES AND COUPLINGS IN NUCLEAR MATTER AND INCOMPRESSIBILITY
The role of effective hadron masses and effective couplings in nuclear matter is studied using a generalized effective Lagrangian for σ-ω model. A simple relation among the effective masses, the effective couplings and the incompressibility K is derived. Using the relation, it is found that the effective repulsive and the effective attractive forces almost cancel each other out at the normal density. Inversely, if this cancellation is almost complete, K is 250~350 MeV.
