Consequences of increased hypertriton binding for s-shell Λ-hypernuclear systems

NUCLEAR STRUCTURE 3,5H; analyzed spin-singlet and spin-triplet scattering lengths for 3H hypernucleus from Λp data, binding energies for 3H and 5H hypernuclei for several different interaction strengths, ratio of the hypertriton excited state lifetime to the free Λ lifetime. Pionless effective field theory (EFT) approach at leading order for s-shell hypernuclei, constrained by the binding energies of the 0+ and 1+ states of 4H hypernucleus. Comparison with experimental binding energies from emulsion data, and from STAR collaboration. Relevance to anticipated measurements of the Λd correlation function at ALICE2CERN and new experiments at MAMI and J-PARC, JLAB, and ELPH facilities for more precise determination of binding energy of hypertriton, and its excited state.
