We calculate the mass spectra of the singly charmed baryons (, , and ) using the hypercentral constituent quark model (hCQM). The hyper color Coulomb plus linear potential is used to calculate the masses of positive (up to ) and negative (up to ) parity excited states. The spin-spin, spin-orbital and tensor interaction terms are also incorporated for mass spectra. We have compared our results with other theoretical and lattice QCD predictions for each baryon. Moreover, the known experimental results are also reasonably close to our predicted masses. By using the radial and orbital excitation, we construct Regge trajectories for the baryons in the (n, M2) plane and find their slopes and intercepts. Other properties of these baryons, like magnetic moments, radiative transitions and radiative decay widths, are also calculated successfully.

Abstract. Mass spectra of excited states of the singly charmed baryons are calculated using the hypercentral description of three body system. The baryon consist of a charm quark and light quarks (u, d and s) are studied in the framework of QCD motivated constituent quark model. The form of confinement potential is hyper coloumb plus power potential with potential index ν, varying from 0.5 to 2.0. The first order correction to the confinement potential is also incorporated in this approach. The radial as well as orbital excited state masses of Σ We have incorporated spin-spin, spin-orbit and tensor interactions perturbatively in the present study. The semielectronic decay of Ωc and Ξc are also calculated using the spectroscopic parameters of these baryons. The computed results are compared with other theoretical predictions as well as with the available experimental observations. We also construct the Regge trajectory in (nr, M 2 ) and (J, M 2 ) plane for these baryons.

We present the mass spectra of radial and orbital excited states of singly heavy bottom baryons;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 triply heavy flavour baryons are studied using the Quark-diquark description of the threebody system. The confinement potential for present study of triply heavy flavour baryons is assumed as coulomb plus power potential with power index ν. We have solved Schrodinger equation numerically to calculate the masses of triply heavy flavour baryons. The masses and magnetic moments of triply heavy flavour baryons are computed for different power indices, ν, starting from 0.4 to 1.0. The predicted masses and magnetic moments are in good agreement with other theoretical predictions. PACS. 12.39.-x Phenomenological quark models -12.39.Jh Nonrelativistic quark model -14.20.-c Baryons
