© 2014 The physical society of the republic of china. The recently developed low momentum nucleon-nucleon potential Vlow-k obtained from integrating the high momentum part of a realistic potentials is adopted in the particleparticle hole-hole ring diagram calculation to study nuclear properties. The elementary NN interaction is chosen to be a chiral N3LO two-nucleon potential V2N with the inclusion of an in-medium three-nucleon (NNN) force V3N. The nuclear binding energy is accurately reproduced. Without this three-nucleon force, the nuclear binding energy is too weak, as is already known. The correction from the ring diagrams of order higher than 1 cannot be ignored. Comparison with old results using the Skyrme effective interactions is also made and discussed.
