Abstract

The present study is dedicated to light-strange Λ\Lambda with strangeness S=-1, isospin I=0; Σ\Sigma with S=-1, I=1 and Ξ\Xi baryon with S=-2 and I=12I=\frac{1}{2}. In this article, hypercentral Constituent Quark Model with linear confining potential has been employed along with first order correction term to obtain the resonance masses for nearly upto 4 GeV. The calculated states include 1S-5S, 1P-4P, 1D-3D, 1F-2F and 1G (in few case) along with all the possible spin-parity assignments. Regge Trajectories have been explored for the linearly of the calculated masses for (n,M2)(n,M^{2}) and (J,M2)(J,M^{2}) respectively. Magnetic moments have been intensively studied for ground state spin 12\frac{1}{2} and 32\frac{3}{2}, in addition to the configuration mixing for first negative parity state for Ξ\Xi. Lastly, transition magnetic moment and radiative decay width have been presented.
