    "abstract": "A system of nontopological solitons interacting through scalar and vector\nmeson exchange is used to model nuclear matter. The models studied are of the\nFriedberg-Lee type, which exhibit dynamical bag formation due to the coupling\nof quarks to a scalar composite gluon field. It is shown that the chiral\nchromodielectric model gives the best fit to the empirical data. The presence\nof the scalar meson guarantees saturation and an increase of the proton charge\nradius with nuclear density consistent with the EMC effect.",
