Hadron mass relations in a charmed quark model with broken SU(8) symmetry

Abstract

It is assumed that charmed hadrons exist, and, together with the usual hadrons, can be classified in representations of SU(8). Hadron masses are assumed to arise from quark masses plus two-body interactions between quarks. Mass relations among the hadrons are obtained. It is estimated that charmed vector mesons have masses about 2 GeV and that charmed baryons have masses between 2.2 and 5 GeV.
