"Analysis of the [56,2+] Baryon Masses in the 1/Nc Expansion"
J.L. Goity, C. Schat and N.N. Scoccola
Phys. Lett. B 564(1-2) (2003) 83-89
The mass spectrum of the positive parity [56,2+] baryons is studied in the 1/Nc expansion up to and including O1/Nc effects with SU(3) symmetry breaking implemented to first order. A total of eighteen mass relations result, several of which are tested with the available data. The breaking of spin-flavor symmetry is dominated by the hyperfine interactions, while spin-orbit effects are found to be small.
