“…The excited states masses of singly, doubly and triply heavy baryons in both charm and bottom sector are in good agreement with other theoretical predictions as well as with the recent experimental outcomes [37][38][39][40][41][42][43]. Further, the magnetic moments of heavy baryons are also determined at L=0 and radiative decays, strong decays are calculated [44]. Moreover, with the help of the Regge trajectories the unknown quantum states and J P values are also identified.…”

We present the masses of N baryon upto 3300 MeV. The radial and orbital excited states are determined using hypercentral constituent quark model with first order correction. The obtained masses are compared with experimental results and other theoretical prediction. The Regge Trajectories are also determined in (n, M 2 ) and (J, M 2 ) planes. Moreover, the magnetic moments for J P = 1 2 + , 1 2 − are calculated. We also calculate the N π decay width of excited nucleons.

Excited states masses of the strange singly charmed baryons are calculated using the non-relativistic approach of hypercentral Constituent Quark Model (hCQM). The hyper-Coulomb plus screened potential is used as a confinement potential with the first order correction. The spin-spin, spinorbit and spin-tensor interaction terms are included perturbatively. Our calculated masses are allowed to construct the Regge trajectories in both (n r , M 2 ) and (J, M 2 ) planes. The mass spectra and the Regge trajectories study predict the spin-parity of Ξ c (2970) +/0 , Ξ c (3080) +/0 , Ξ c (3123) + , Ω c (3000) 0 and Ω c (3119) 0 baryons. Moreover, the strong one pion decay rates of the isodoublet states of Ξ c (2645), Ξ c (2790) and Ξ c (2815) are analyzed in the framework of Heavy Hadron Chiral Perturbation Theory (HHChPT). Also, the ground state magnetic moments and the radiative decay rates based on the transition magnetic moments are calculated in the framework of constituent quark model.

In this article, we study the radial states as well as orbital states mass spectra of the nonstrange baryons from bottom family utilizing hypercentral Constituent Quark Model(hCQM), a non-relativistic approach by employing screened potential as confining potential with color Coulomb potential. The spin-spin, spin-orbital and tensor interaction are considered for hyperfine splitting calculation. The mass spectra calculated and compared with other theoretical approaches. The Regge trajectories has been plotted in (J, M 2 ) plane using the calculated mass spectra. Further, the single-pion decay and radiative decay have been described and magnetic moments are determined for the ground state. Keywords Λ 0 b and Σ ± b baryons • Mass spectra • Regge trajectories
