✦ Synopsis

We extend the quark mean-field model to the study of Λ hypernuclei. Without adjusting parameters, the properties of Λ hypernuclei can be described reasonably well. The small spin-orbit splittings for Λ in hypernuclei are achieved, while the Λ single-particle energies in the present model are slightly underestimated as compared with the experimental values. About 3% deviation from the quark model prediction for the ω-Λ couplings is required in order to reproduce the experimental single-particle energies.

We perform a study of infinite hadronic matter, finite nuclei and hypernuclei with an improved method of calculating the effective baryon mass. A detailed study of the predictions of the model is made in comparison with the available data and the level of agreement is generally very good. Compariso
