We wish to construct energy-independent potentials, which are non-local in genera

3、l. These potentials will be constructed from Bethe-Salpeter wave functions in wide range of energy region. Energy-dependence, which enters from naïve treatments, will be transmuted into non-locality via derivative expansion. As a first step toward this direction, we generate a potential at E50

4、MeV by using spatially anti-periodic boundary condition, and compare it with the one at E0 MeV. So far, small energy dependence is found at short distance, which suggests effectiveness of the derivative expansion. For hyperonic sector, we calculate the potential and scattering length of N system. Th

5、e present preliminary results are qualitatively consistent with the empirical data, i.e., the N interaction is weakly attractive and the spin dependence is very small.研究成果公開研究成果公表口頭研究発表件數(shù)査読學(xué)術(shù)論文數(shù)論文數(shù)他（投稿中含）33272成果公表（枠番號(hào)記入願(yuàn)。）口頭研究発表1.
