    "abstract": "This paper presents the Extended-Soft-Core (ESC) potentials ESC04a-d for\nbaryon-baryon channels with total strangeness $S=-2$. For these channels no\nexperimental scattering data exist, and alsothe information from hypernuclei is\nvery limited.The potential models for $S=-2$ are based on SU(3) extensions of\npotential models for the $S=0,-1$ sectors, which are fitted to experimental\ndata. Flavor su(3)-symmetry is broken \u0027kinematically\u0027by the masses of the\nbaryons and the mesons.Moreover, in ESC04a,b aldo the coupling constants are\nbroken, albeit in a well defined way using the $^3P_0$ quark-antiquark pair\ncreation model as a guidance. But the fit to the S=0 and $S=-1$ sectors\nprovides the necessary constraints to fix all free parameters.Therefore, the\npotentials for the $S=-2$ sectors do not contain additional free parameters,\nwhich situation is similar to the soft-core one-boson-exchange NSC97-models.\nVarious properties of the potentials are illustrated by giving results for\nscattering lengths, bound states, phase-parameters, and total cross sections.\nThe features of $\\Xi$-hypernuclei predicted by ESC04d are studied on the basis\nof the G-matrix approach.",
