Production and structure of the 4ΣHe hypernucleus
Description
The Σ-hypernuclear bound state 4ΣHe with Jπ=0+ and T∼1/2(99%) is calculated by using a realistic ΣN interaction, with results which are in agreement with the experimental observation at KEK. A complex nucleus-Σ potential derived has a repulsion near the nuclear center in its real part, which suppresses the ΣN→ΛN conversion. To get definitive information on the width and the structure of the 4ΣHe bound state, its production by 4He(K-, π±) reactions in flight at pK=600MeV/c are investigated theoretically within the DWIA framework.
