Lattice QCD calculation has been performed with Blue Gene/L at KEK under the “ Large scale simulation program ” at KEK. We thank PACS-CS Collaboration and ILDG/JLDG for providing us the 2 + 1 flavor gauge configurations [18,22,23] . We are grateful for the authors and maintainers of CPS++ [24] , a modified version of which is used for measurement done in this work. This research is supported in part by Grant-in-Aid for Scientific Research on Innovative Areas (Nos. 2004:20105001 , 20105003 ) and for Scientific Research(C) 23540321 , JSPS 21⋅5985 and SPIRE (Strategic Program for Innovative Research).

N2 - Imaginary-time Nambu-Bethe-Salpeter (NBS) wave function is introduced to extend our previous approach for hadron-hadron interactions on the lattice. Scattering states of hadrons with different energies encoded in the NBS wave function are utilized to extract non-local hadron-hadron potential. "The ground state saturation", which is commonly used in lattice QCD but is hard to be achieved for multi-baryons, is not required. We demonstrate that the present method works efficiently for the nucleon-nucleon interaction (the potential and the phase shift) in the S01 channel.
