摘要：
The LHCb Experiment at CERN has observed a doubly-charmed baryon xi(++)(cc) = ccu with a mass of 3621.40 +/- 0.78 MeV, consistent with many predictions. We use the same methods that led us to predict M(xi(cc), J(p) = 1/2(+)) = 3627 +/- 12 MeV and M(xi(*)(cc), J(p)=3/2(+))=3690 +/- 12MeV to predict M(Omega(+)cc, J(P) = l/2(+)) = 3692 = +/- 16 MeV and M(Omega(*)cc, J(p) = 3/2(+)) = 3756 +/- 16 MeV. Production and decay are discussed briefly, and predictions for M(Omega(bc)) and M(Omega(bb)) are included.
