Quark Contribution to the Magnetic Moments of Hypernuclei with Closed Core +Λ Configuration

Abstract

Abstract: We have estimated the magnetic moments of these nuclei  in the Hybrid Quark Model. When the Λ-hyperon forms a six-quark bag with the core nucleons, the Schmidt values get modified. In the case of hypernuclei with closed core+configuration, the quark correction ranges between 0.1 to 2.1 %, the deviation being largest for. Earlier studies have shown that the comparison of predicted magnetic moments, with those of others calculations results very close to Schmidt value and has shown that correction arising due to various renormalization processes tend to cancel each other Thus any departure from the Schmidt values in the observed magnetic moments can be attributed to the quark effects.

Keywords: Hypernuclei, six-quark probability, Schmidt values, hybrid quark model (HQM)
