2+1 Flavor QCD Results of Nuclear Forces

2+1 flavor QCD results of nuclear forces are reanalyzed by using a recently developed method which has a remarkable advantage that it can calculate nuclear forces without relying on the ground state saturation of Nambu-Bethe-Salpeter wave functions. Resulting potentials are parametrized by fit functions which mimic the functional form of AV18. These potentials are used to calculate the scattering phases.
