Abstract

Based on the chiral SU(3) quark model， the nonlocal Σ-N interaction and Σ3 He core interaction are investigated with two theories by the resonating group method. Then the bound energy BΣ of hypernuclei 4ΣHe is calculated with the interaction. It is shown that the chiral SU(3) quark model can well describe not only the nonlocal ΣN interaction but also Σcore interaction in the frame of two theories. At the same time， our calculation result of the bound energy BΣ of 4ΣHe is in agreement with the experiment data basically too.
