Understand

Recent progress of lattice QCD study of nuclear forces (potentials) is reviewed.

  • Scattering phase shift is an important observable for two particle system.
  • In lattice QCD, phase shifts are calculated from long distance behavior of Bethe-Salpeter (BS) wave functions by Luescher's finite volume method.
  • For applications to nuclear physics of multi-nucleon system, it is more advantageous to convert the information of phase shifts in the form of potentials.
