Abstract
The charge symmetry breaking and charge independence breaking N-N ^1S_0 scattering length differences, Delta a_{CSB} and Delta a_{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 Delta a_{CSB} and Delta a_{CIB} values can be reproduced with model parameters constrained by the hadron isomultiplet mass splitting.
