Excited state mass spectra of doubly heavy $$\Xi $$ Ξ baryons

Abstract

In this paper, the mass spectra are obtained for doubly heavy baryons, namely, + cc , ++ cc , − bb , 0 bb , 0 bc and + 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 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.

Deuteron-like states composed of two doubly charmed baryons

“…In Refs. [55][56][57][58][59][60], the mass of the doubly charmed baryon was estimated from 3511 to 3685 MeV. The particular isospin splitting of the states observed by SELEX was discussed in Ref.…”

Mass spectra of triply beauty $\Omega_{bbb}$ baryon

“…In heavy sector of this baryon, very recently, five states of singly charmed Ω baryon is published [2]. We have already determined the masses of ground and excited states of Ω c , Ω b , Ω cc , Ω bb , Ω bc , Ω ccc , Ω bbb baryons with their isospin splittings in our previous work [3,4,5,6,7,8,9]. Ω baryon with three heavy beauty quarks is experimentally still unknown [10].…”
