We investigate the existence of bound states in systems with
baryons using the Jacobi NCSM approach in combination with chiral NN and
N interactions. We find three shallow bound states for the NNN
system (with
,
and
) with quite similar binding energies. The
and
hypernuclei are also clearly bound with respect to the thresholds
and
, respectively. The binding of all these
systems is predominantly due to the attraction of the chiral
N potential in the
channel. A perturbative estimation suggests that the decay widths of all the observed states could be rather small.
