Excited State Mass spectra and Regge trajectories of Bottom Baryons

Abstract

We present the mass spectra of radial and orbital excited states of singly heavy bottom baryons; ${\Sigma }_b^{+},{\Sigma }_b^{-},{\Xi }_b^{-},{\Xi }_b^0,{\Lambda }_b^0$ and ${\Omega }_b^{-}$. 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 ${\Omega }_b$ and ${\Xi }_b$ 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.
