摘要
In this paper, we presented the mass spectra of the doubly heavy O baryons containing one light (strange) quark and two heavy (charm and bottom) quarks. Our predicted masses can be considered to determine the J(p) value for the resonances detected by experimental facilities in future. The masses of ground and excited states (1 S-6 S, 1P-3P, 1D-2D, 1F-2F) are calculated for all possible J(p) values, using the Hypercentral Constituent Quark Model (hCQM), by employing screened potential as confining potential with color-Coulomb potential. Regge trajectories are also plotted in (J, M-2) plane for natural and unnatural parities. Doubly heavy Omega states are not declared yet by any experimental facility. We compared our results to the predictions gained from other theoretical approaches, and we found that our predictions are quite close to those of them. Other properties such as magnetic moment (for spin state 1/2 and 3/2) and radiative decay width are calculated using the enumerated masses.
