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.
