Self-consistent description of hypernuclei in the quark-meson coupling model
K. Tsushima, K. Saito, A. W. Thomas
Abstract
The quark-meson coupling (QMC) model, which has been successfully used to describe the properties of both finite nuclei and infinite nuclear matter, is applied to a study of hypernuclei. With the assumption that the (self-consistent) exchanged scalar, and vector, mesons couple only to the u and d quarks, a very weak spin-orbit force in the -nucleus interaction is achieved automatically. This is a direct consequence of the SU(6) quark model wave function of the used in the QMC model. Possible implications and extensions of the present investigation are also discussed.
