Full-Coupled Channel Approach to Doubly Strange $s$-Shell Hypernuclei

H. Nemura, S. Shinmura, Y. Akaishi +1

We describe {\it ab initio} calculations of doubly strange, $S=-2$, $s$-shell hypernuclei (${}_{\Lambda \Lambda }^4$H, ${}_{\Lambda \Lambda }^5$H, ${}_{\Lambda \Lambda }^5$He and ${}_{\Lambda \Lambda }^6$He) as a first attempt to explore the fe…
