N2 - We have extended our method to derive the Faddeev equations of the coupled NΛΛ-ΞNN system by including the and channels. We have applied them to the bound-state problem of the strangeness -2 three-body system. As in our previous publication, we use as input the two-body interactions obtained from a chiral constituent quark model, exploring different parametrizations of the quark-quark interacting potential. We have found that the main contribution arises from the components. The net effect of the new channels is a reduction in the binding energy of the strangeness -2 hypertriton by between 80 and 150 keV, although it remains bound for all parametrizations explored.
