Spectrum and Bethe-Salpeter amplitudes of Ω baryons from lattice QCD

The Ω baryons with JP= 3/2^±, 1/2^± are studied on the lattice in the quenched approximation. Their mass levels are ordered as M3/2＋〈 M3/2- 0≈M1/2-〈 M1/2＋, as is expected from the constituent quark model. The mass values are also close to those of the four Ωstates observed in experiments. We calcula...
