  "abstract": "Recent experiments have presented more accurate data on the $\\Lambda\\Lambda$-binding energies of a few $\\Lambda\\Lambda$- hypernuclei. This is important as the $\\Lambda\\Lambda$- bond energies ($\\Delta B_{\\Lambda\\Lambda}$) of double-$\\Lambda$ hypernuclei provide a measure of the in-medium strength of the $\\Lambda\\Lambda$ interaction. A mass formula, optimized with the newly available $\\Lambda\\Lambda$ binding energy data, is used to estimate the binding energy and bond energy over a wide range of hypernuclei. The $\\Delta B_{\\Lambda\\Lambda}$ values calculated with this mass formula are in good agreement with the experimental data, predictions of the quark mean-field (QMF) model and the relativistic mean-field (RMF) model as well. The $\\Lambda\\Lambda$-bond energy is found to diminish with neutron numbers, approaching zero near the neutron-drip line. In this formalism, the calculated binding energy difference in mirror nuclei arises from the Coulomb contributions and can be utilized to extract the Coulomb-corrected charge symmetry breaking effect.",
