Abstract

The ∑-hypernuclear bound state 4∑ He with J π=0+ and T~½(99%) is calculated by using a realistic ∑N interaction, with results which are in agreement with the experimental observation at KEK. A complex nucleus-∑ potential derived has a repulsion near the nuclear center in its real part, which suppresses the ∑N→ΛN conversion. To get definitive information on the width and the structure of the 4∑ He bound state, its production by 4He(K−,π ∓) reactions in flight at pk=600MeV/c are investigated theoretically within the DWIA framework.
