Spectroscopy of light $N^{\ast }$ baryons

Abstract

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 $J^P={\frac{1}{2}}^{+},{\frac{1}{2}}^{-}$ are calculated. We also calculate the $N\pi$ decay width of excited nucleons.
