5ΛΛH and 5ΛΛHe hypernuclei reexamined in halo/cluster effective theory

NUCLEAR STRUCTURE 5H, 5He; calculated three-body binding energies of 5H and 5He double-Λ hypernuclear mirror partners, double-hyperon separation energies, scattering length for 4H-Λ and 4He-Λ scattering. Calculations based on LO pionless effective field theory (EFT) and many-body analysis using the stochastic variational method (SVM), with the hypernuclear systems treated as three-particle halo-bound clusters, ΛΛ+3H and ΛΛ+3He. 4H, 4He; compiled experimental data for hypernuclei from recent spectroscopic measurements at MAMI and J-PARC collaborations. Relevance to results on hypernuclei in future experiments at PANDA and CBM at FAIR, and JPARC-P75.
