本文介绍了一种从格点QCD的Bethe-Salpter振幅中提取核子-核子（N-N）势的方法。该方法被应用到两个核子的晶格淬火QCD模拟。通过解开S-态和ID-态之间的混合，我们得到了中心势和张量势的速度展开的领先顺序。非局部N-N势详细分析了势的空间结构和夸克质量依赖性。
We present full accounts of a method to extract nucleon-nucleon (N N) potentials from the Bethe-Salpter amplitude in lattice QCD. The method is applied to two nucleons on the lattice with quenched QCD simulations. By disentangling the mixing between the S-state and the ID-state, we obtain central and tensor potentials in the leading order of the velocity expansion of the. non-local N N potential. The spatial structure and the quark mass dependence of the potentials are analyzed in detail.
