摘要

【正】 The N-N ¹S₀ scattering length differences Δα_CSB and Δα_CIH of the charge symmetrybreaking and charge independence breaking are calculated by a resonating group method with aquark cluster model.By adding the QED-QCD interference effect to the quark mass differenceand the electromagnetic interaction,the Δα_CSH and Δα_CIH can be reproduced with modelparameters constrained by the hadron isomultiplet masses.
