Description
1/Nc expansion in QCD (with Nc the number of colours) suggests using a potential from meson sector (e.g. Richardson) for baryons. For light quarks a σ field has to be introduced to ensure chiral symmetry breaking (χSB). It is found that nuclear matter properties can be used to pin down the χSB-modelling. All masses, MN, mσ, mω are found to scale with density. The equations are solved self consistently. (author). 29 refs, 2 tabs
