    "abstract": "The $\\Lambda\\Lambda$-$\\Xi N$-$\\Sigma\\Sigma$ coupling in\n$^{~6}_{\\Lambda\\Lambda}$He is studied with the [$\\alpha$ + $\\Lambda$ +\n$\\Lambda$] + [$\\alpha$ + $\\Xi$ + $N$] + [$\\alpha$ + $\\Sigma$ + $\\Sigma$] model,\nwhere the $\\alpha$ particle is assumed as a frozen core. We use the Nijmegen\nsoft-core potentials, NSC97e and NSC97f, for the valence baryon-baryon part,\nand the phenomenological potentials for the $\\alpha-B$ parts ($B$=$N$,\n$\\Lambda$, $\\Xi$ and $\\Sigma$). We find that the calculated $\\Delta\nB_{\\Lambda\\Lambda}$ of $^{~6}_{\\Lambda\\Lambda}$He for NSC97e and NSC97f are,\nrespectively, 0.6 and 0.4 MeV in the full coupled-channel calculation, the\nresults of which are about half in comparison with the experimental data,\n$\\Delta B^{exp}_{\\Lambda\\Lambda}=1.01\\pm0.20^{+0.18}_{-0.11}$ MeV.\nCharacteristics of the $S=-2$ sector in the NSC97 potentials are discussed in\ndetail.",
