Abstract

We present the results of the effects of various mechanisms on the quark level, including QED-QCD interference effect, on isospin violation in 1S0 NN scatterings with the new sets of strength parameters obtained by fitting to mass splittings in the baryon isomultiplets listed in the most recent PDG compilation. We also give the matrix elements of the various potential operators which would be useful to study of these charge dependent effects in finite nuclei.
