QED-QCD interference effect on the charge-dependent N-N interaction

摘要

The charge symmetry breaking and charge independence breaking N-N S-1(0) scattering length differences, Deltaa(CSB) and Deltaa(CIB), 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 Deltaa(CSB) and Deltaa(CIB) values can be reproduced with model parameters constrained by the hadron isomultiplet mass splitting.
