Abstract: (APS)

Assuming that hadron mass differences result from intrinsic quark mass differences and two-body spin-spin interactions together with the Coulomb and magnetic interactions in an SU(8) model, we determine the charmed-hadron mass spectrum. A complete set of mass relations is derived for the baryon electromagnetic mass differences. In addition to the prediction of charmed-baryon mass differences a modified SU(6) relation is found to be well satisfied. D+−D0 and D*+−D*0 are estimated to be about 5.2 MeV and 3.7 MeV, respectively.
