In this paper, we study the properties of triply charm and triply bottom baryon. The mass spectra of these baryons are calculated in nonrelativistic constituent quark model with Coulomb plus screened potential. Several states S , P , D and F of the Ω c c c and Ω b b b baryons with quantum number J P = 1 2 ± , 3 2 ± , 5 2 ± , 7 2 ± are determined. Regge trajectories are also plotted to determine the quantum number of baryons. Moreover, the magnetic moments are calculated for J P = 3 2 + . [ABSTRACT FROM AUTHOR]

In this article, we study the radial and orbital masses of Λ b and Σ b baryons. The hypercentral Constituent Quark Model(hCQM) is employed with screened potential. The calculated mass spectra are compared with the latest results of LHCb collaboration and CMS collaboration as well as with the other theoretical approaches and are found to be in good accordance. The single-pion strong decay widths are calculated for P, S and D- wave transitions. The magnetic moments, transition magnetic moments and radiative decays are also determined.

In this paper, we enumerated ground and excited state masses of singly heavy bottom-strange baryons using the hypercentral constituent quark model (hCQM). The screening potential is used with color-Coulomb potential, as the confining potential. We determine the possible J P values to recently observed excited states like, Ξ b (6 1 0 0) , Ξ b (6 2 2 7) , Ξ b (6 3 2 7) , Ξ b (6 3 3 3) and four Ω b (6 3 1 6 , 6 3 3 0 , 6 3 4 0 , 6 3 5 0) states. The Regge trajectories are plotted in (J , M 2) plane to assign the J P values and quantum numbers to recently observed states. Using the calculated spectroscopic data, properties such as magnetic moment, transition magnetic moment, radiative decay width, and strong decay width are also investigated for all singly heavy bottom-strange baryonic system.

We study the masses of radial and orbital excited states of nonstrange singly charmed baryons in the framework of hypercentral Constituent Quark Model (hCQM). To obtain the mass spectra, the Coulomb plus screened potential is employed with the first order correction, which gives a relativistic effect of order O (1/m). The spin-spin, spin-orbit and tensor interactions are included (perturbatively as a spin dependent potential) in order to generate the splitting in mass spectra. We compare our computed mass spectra of nonstrange singly charmed baryons with the other theoretical predictions as well as with the experimental observations. We construct the Regge trajectories of these baryons in the (J, M2) plane. Further, we analyze the strong one pion decay rates for S, P and the D-wave transitions in the framework of Heavy Hadron Chiral Perturbation Theory (HHChPT). Moreover, the electromagnetic properties like magnetic moments, transition magnetic moments and the radiative decay widths are determined for the ground state of these baryons in the constituent quark model.

The excited state masses of triply charm and triply bottom $\Omega$ baryons are exhibited in the present study. The masses are computed for 1 S-5 S, 1 P-5 P, 1 D-4 D and 1 F-2 F states in the Hypercentral Constituent Quark Model (hCQM) with the hyper Coulomb plus linear potential. The triply charm/bottom baryon masses are experimentally unknown so that the Regge trajectories are plotted using computed masses to assign the quantum numbers of these unknown states.

We present the mass spectra of radial and orbital excited states of singly heavy bottom baryons; Σ b + , Σ b − , Ξ b − , Ξ b 0 , Λ b 0 and Ω b − . The QCD motivated hypercentral quark model is employed for the three body description of baryons and the form of confinement potential is hyper Coulomb plus linear. The first order correction to the confinement potential is also incorporated in this work. The semi-electronic decay of Ω b and Ξ b are calculated using the spectroscopic parameters of the baryons. The computed results are compared with other theoretical predictions as well as with the available experimental observations. The Regge trajectories are plotted in ( n , M 2 ) plane.

The mass spectra of singly bottom baryon Ωb- is determined using the Hypercentral Constituent Quark Model. The confinement potential is assumed in the hyper central co-ordinates as hyper coulomb plus power potential. The ground state mΩb-=6048.8±3.2 MeV with JP=12+ is found experimentally till now. Our calculated mass spectra for Ωb- is obtained by varying potential index ν value from 0.5 to 2.0 for ground and radial excited states while orbital excited states are determined at ν=1.0. Lattice QCD results and other recent theoretical predicted masses are close to our obtained results. Using these mass spectra we plotted Regge trajectories in (n, M2) and (J, M2) planes. The trajectories are useful to determine the unknown JP values of particular states. [ABSTRACT FROM AUTHOR]

In this paper, we will discuss the triply heavy baryon Ωbbc. This baryon is experimentally unknown till the date. We use hypercentral constituent quark model with Coulomb plus linear potential along with (1/m) correction to it. We extract the masses from S state to F state and present them with all iso-spin splittings. We also plot the Regge trajectories and determined slope and intercepts. Ground state magnetic moments are also calculated. [ABSTRACT FROM AUTHOR]
