摘要The parity-odd effect in the standard model weak neutral current reveals itself in the long-range parity-violating nuclear potential generated by the pion exchanges in the Delta I = 1 channel with the parity-odd pion-nucleon coupling constant h(pi)(1). Despite decades of experimental and theoretical efforts, the size of this coupling constant is still not well understood. In this Letter, we derive a soft-pion theorem relating hR and the neutron-proton mass splitting induced by an artificial parity-even counterpart of the Delta I = 1 weak Lagrangian and demonstrate that the theorem still holds exact at the next-to-leading order in the chiral perturbation theory. A considerable amount of simplification is expected in the study of h(pi)(1) by using either lattice or other QCD models following its reduction from a parity-odd proton-neutron-pion matrix element to a simpler spectroscopic quantity. The theorem paves the way to much more precise calculations of h(pi)(1), and thus a quantitative test of the strangeness-conserving neutral current interaction of the standard model is foreseen.
