Double Charm Baryons Ξ_cc^(++),Ξ_cc^+,andΩ_cc^+

An application of the first-order model of Zel'dovich and Sakharov is used to determine the theoretical double charm baryon masses for the Ξ_cc^(++),Ξ_cc^+,andΩ_cc^+. The primitive spin structure of the model predicts 1/2+ and 3/2+ assignments for these double charm baryons. A first-order Ξ_cc^(++) baryon mass is calculated to be within about 2% of the experimental value. The Ξ_cc^+ was recently reported, but no definitive mass or spin assignment were provided. A Ω_cc^+ has also been postulated. Theoretical masses for the Ξ_cc^+,andΩ_cc^+ baryons are also provided in this paper. The calculated masses depend on the Jπ value following the formulation of the first-order model.
