2 Nov 1999 | | Journal: | Mod.Phys.Lett. A16 (2001) 1417-1426 | | Subject: | nucl-th | | Affiliation: | Nanjing U. of Sci. and Tech.), Jia-Lun Ping (Nanjing Normal U.), Fan Wang (Nanjing U.) and T. Goldman (Los Alamos | | 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. | | Source: | arXiv, nucl-th/9911008 | | Services: | Forum | Review | PDF | Favorites | |
