Pionic Contributions in a Quark Model of Nucleons and Nuclei

A successful relativistic quark model of small nuclei[1] did not include long-range effects of pion exchanges between quarks. We add these contributions to themodel with a short-range cutoff (to avoid double counting). We report on the changes induced in model parameters and binding energies. [1]T. Goldman, K.R.
