“…[39], approximate but explicit calculations were performed for the decay process of 7 Ξ H, and a large branching ratio decaying to 5 ΛΛ H is obtained. Based on this estimate of high branching ratio to form 5 ΛΛ H, Fujioka et al proposed a new experiment at J-PARC (P75) [40]. Since the branching ratio is crucial to determine the feasibility of the experiment, it is valuable to evaluate the branching ratio in different approaches.…”

We investigate double Λ hyperfragment formation from the statistical decay of double Λ compound nuclei produced in the Ξ − absorption at rest in light nuclei, 12 C, 14 N and 16 O. We examine the target and the ΛΛ bond energy dependence of the double Λ hyperfragment formation probabilities, especially of those double hypernuclei observed in experiments. For the 12 C ( 14 N) target, the formation probabilities of 6 ΛΛ He and 10 ΛΛ Be ( 13 ΛΛ B) are found to be reasonably large as they are observed in the KEK-E373 (KEK-E176) experiment. By comparison, for 16 O target, the formation probability of 11 ΛΛ Be is calculated to be small with ∆B ΛΛ consistent with the Nagara event. We also evaluate the formation probability of 5 ΛΛ H from a Ξ − -6 He bound state, 7 Ξ H.

We investigate double $\Lambda$ hyperfragment formation from the statistical decay of double $\Lambda$ compound nuclei produced in the $\Xi^-$ absorption at rest in the light nuclei $^{12}\mathrm{C}$, $^{14}\mathrm{N}$, and $^{16}\mathrm{O}$. We examine the target and the $\Lambda\Lambda$ bond energy dependence of the double $\Lambda$ hyperfragment formation probabilities, especially of those double hypernuclei observed in experiments. For the $^{12}\mathrm{C}$ ($^{14}\mathrm{N}$) target, the formation probabilities of $^{\,\;\;6}_{\Lambda\Lambda}\mathrm{He}$ and $^{\;10}_{\Lambda\Lambda}\mathrm{Be}$ ($^{\;13}_{\Lambda\Lambda}\mathrm{B}$) are found to be reasonably large as they are observed in the KEK-E373 (KEK-E176) experiment. By comparison, for the $^{16}\mathrm{O}$ target, the formation probability of $^{\;11}_{\Lambda\Lambda}\mathrm{Be}$ is calculated to be small with $\Delta B_{\Lambda\Lambda}$ consistent with the Nagara event. We also evaluate the formation probability of ${}^{\,\;\;5}_{\Lambda\Lambda}\mathrm{H}$ from a $\Xi^-$–${}^{6}\mathrm{He}$ bound state, ${}^{7}_{\Xi}\mathrm{H}$.
