关 键 词:bond energy hypernuclei core polarization
摘 要:To provide guideline for near future experiments proposed at PANDA@FAIR and J-PARC,the∧∧bond energy in double-∧hypernuclei are explored with a new effective∧N interaction PK1-Y1,which is obtained by optimizing both hyperon binding energy and spin-orbit splitting within a relativistic mean field approach. The AA bond energy under case with onlyσ,ωmesons exchanged is found to be consistent with a perturbation calculation based on a Skyrme-Hartree-Fock *** the strange mesons such as scalarσ and vectorΦ,the net contribution fromσ andΦhas sharply reduced the∧∧bond *** addition,core polarization effect is shown tiny in heavier double-∧hypernuclei.
