AB  - We investigate the existence of bound Ξ states in systems with A=4−7 baryons using the Jacobi NCSM approach in combination with chiral NN and ΞN interactions. We find three shallow bound states for the NNNΞ system (with (Jπ,T)=(1+,0), (0+,1) and (1+,1)) with quite similar binding energies. The 5ΞH(12+,12) and 7ΞH(12+,32) hypernuclei are also clearly bound with respect to the thresholds 4He+Ξ and 6He+Ξ, respectively. The binding of all these Ξ systems is predominantly due to the attraction of the chiral ΞN potential in the 33S1 channel. A perturbative estimation suggests that the decay widths of all the observed states could be rather small.
