Hypernuclear constraints on the existence and lifetime of a deeply bound H dibaryon
We study to what extent the unique observation of ΛΛ hypernuclei by their weak decay into known Λ hypernuclei, with lifetimes of order 10−10 s, rules out the existence of a deeply bound doubly-strange (S = − 2) H dibaryon. Treating ΛΛ6He (the Nagara emulsion event) in a realistic Λ−Λ−4He three-body...
