QCD-based charge symmetry breaking interaction and the Okamoto-Nolen-Schiffer anomaly

# metadata.dc.description.abstract[].value
An approach is proposed to link the charge symmetry breaking (CSB) nuclear interaction and the low-energy constants in quantum chromodynamics (QCD) by matching the CSB effect in nuclear matter. The resulting CSB interaction is applied to study the Okamoto-Nolen-Schiffer anomaly, still lacking a satisfactory microscopic understanding, on the energy differences of mirror nuclei by taking 17F−17O, 15O−15N, 41Sc−41Ca, and 39Ca−39K as typical examples. The magnitude and sign of the QCD-based CSB interactions are found to resolve the anomaly successfully within theoretical uncertainties.
