【 摘 要 】

The authors show that an expansion of nuclear forces about the chiral limit is formally consistent and is equivalent to KSW power counting in the {sup 1}S{sub 0} channel and Weinberg power counting in the {sup 3}S{sub 1}--{sup 3}D{sub 1} coupled channels. Numerical evidence suggests that this expansion converges. The feasibility of making contact between nuclear physics and lattice-QCD simulations is discussed.
