QED-QCD Interference Effect on the Charge Dependent N-N Interaction
Abstract
The charge symmetry breaking and charge independence breaking N-N 1S0 scattering length differences, Delta aCSB and Delta aCIB, are calculated by a resonating group method with a quark cluster model. By adding the QED-QCD interference effect to the quark mass difference and the electromagnetic interaction, the Delta aCSB and Delta aCIB values can be reproduced with model parameters constrained by the hadron isomultiplet mass splitting.
