Study of $\hat{I}›$ hypernuclei in the quark mean field model

Abstract

We extend the quark mean field model to the study of $\hat{I}›$ hypernuclei. Without adjusting parameters, the properties of $\hat{I}›$ hypernuclei can be described reasonably well. The small spin-orbit splittings for $\hat{I}›$ in hypernuclei are achieved, while the $\hat{I}›$ 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 $\ddot{I}‰-\hat{I}›$ couplings is required in order to reproduce the experimental single particle energies.
