Description
We computed excited state masses of singly heavy $\Lambda_b^{0}$ baryon in the framework of Hypercentral Constituent Quark Model. We use hyper coloumb plus power potential, varying ($\nu$) from S.R.(1/2) to quadratic(2.0), in the calculation of ground and radial excited state masses. After that, orbital excited states are also determine for linear($\nu$=1.0) potential. We also introduced first order correction to the potential. The ground state $\Lambda_b(5619)^0$ and two orbital excited states $\Lambda_b(5912)^0$ and $\Lambda_b(5920)^0$ are found experimentally and our obtained masses for these states are $m_{\Lambda_b^{0}}(1/2^{+})$= 5620, $m_{\Lambda_b^{0}}$(1/2$^{-})$=5992 MeV and $m_{\Lambda_b^{0}}$(3/2$^{-})$=5980 MeV reasonably close to them. We also compare our results with other theoretical models and they are in good agreement. From this, we also plot Regge trajectories in (n, $M^{2}$) and (J, $M^{2}$) planes for higher excited states.
