Full-coupled channel approach to [formula omitted]s-shell hypernuclear systems

Abstract

We describe full-coupled-channel ab initio calculations among the octet baryons for S = − 2 s-shell hypernuclei, 4 ΛΛ H, 5 ΛΛ H and 6 ΛΛ He. The wave function includes ΛΛ, ΛΣ, NΞ and ΣΣ channels. Minnesota NN, D 2 ′ YN and Nijmegen model D simulated YY interactions are used. This is the first attempt to explore the few-body problem of the full-coupled channel scheme for A = 4 – 6 , S = − 2 multistrangeness hypernuclear systems. Bound state solutions of the ΛΛ hypernuclei, 4 ΛΛ H, 5 ΛΛ H and 6 ΛΛ He, are obtained.
