Abstract

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 {}^{17} \mathrm{F} -17O {}^{17} \mathrm{O} , 15O {}^{15} \mathrm{O} -15N {}^{15} \mathrm{N} , 41Sc {}^{41} \mathrm{Sc} -41Ca {}^{41} \mathrm{Ca} , and 39Ca {}^{39} \mathrm{Ca} -39K {}^{39} \mathrm{K} as typical examples. The magnitude and sign of the QCD-based CSB interactions are found to resolve the anomaly successfully within theoretical uncertainties.
