Abstract
We study the ground-state properties of the
double hyperon for
and
nuclei in a three-body model
. We solve two coupled Faddeev equations corresponding to the three-body configurations
and
in configuration space with the hyperspherical harmonics expansion method by employing the most recent hyperon-hyperon interactions obtained from lattice QCD simulations. Our numerical analysis for
, using three
lattice interaction models, leads to a ground state binding energy in the
MeV domain and the separations
and
in the domains of
fm and
fm, respectively. The binding energy of the double-
hypernucleus
leads to
MeV and consequently to smaller separations
fm and
fm. In addition to geometrical properties, we study the structure of ground-state wave functions and show that the main contributions are from the
wave channels. Our results are consistent with the existing theoretical and experimental data.
