Abstract:

Several experimental investigations have observed parity violation (PV) in nuclear systems - a consequence of the weak force between quarks. We apply the 1/Nc expansion of QCD to the P-violating T-conserving component of the nucleon-nucleon (NN) potential. We show there are two leading-order operators, both of which affect p→p scattering at order Nc. We find an additional four operators at order Nc0sin2θW and six at O(1/Nc). Pion exchange in the PV NN force is suppressed by 1/Nc and sin2θW, providing a quantitative explanation for its nonobservation up to this time. The large-Nc hierarchy of other PV NN force mechanisms is consistent with estimates of the couplings in phenomenological models. The PV observed in p→p scattering data is compatible with natural values for the strong and weak coupling constants: there is no evidence of fine-tuning. © 2015 American Physical Society.
