Abstract
In this paper, the mass spectra are obtained for doubly heavy Xi baryons, namely, Xi _{cc}^{+}, Xi _{cc}^{++}, Xi _{bb}^{-}, Xi _{bb}^{0}, Xi _{bc}^{0} and Xi _{bc}^{+}. These baryons consist of two heavy quarks (cc, bb, and bc) with a light (d or u) quark. The ground, radial, and orbital states are calculated in the framework of the hypercentral constituent quark model with Coulomb plus linear potential. Our results are also compared with other predictions, thus, the average possible range of excited states masses of these Xi baryons can be determined. The study of the Regge trajectories is performed in (n, M^{2}) and (J, M^{2}) planes and their slopes and intercepts are also determined. Lastly, the ground state magnetic moments of these doubly heavy baryons are also calculated.
Highlights
Heavy baryons have two families: and . has a light strange quark, while has up or down quark(s) with two heavy quarks (c and b)
Our previous work [1] exhibited the mass spectra, magnetic moments, and Regge trajectories of doubly heavy baryons, while in the present paper, we established the baryon family with six members
We present our mass spectra results of all doubly heavy baryons in Sect
Summary
Heavy baryons have two families: and . has a light strange quark, while has up or down quark(s) with two heavy quarks (c and b). Our previous work [1] exhibited the mass spectra, magnetic moments, and Regge trajectories of doubly heavy baryons, while in the present paper, we established the baryon family with six members. The Hamiltonian model [9], Regge phenomenology [10,11], lattice QCD [12,13,14,15], QCD sum rules [16,17], the variational approach [18], and many more [19,20,21,22,23,24,25,26,27,28,29,30,31,32,33] have provided new results in the field of doubly heavy baryons. 2. We present our mass spectra results of all doubly heavy baryons in Sect.
