Spectroscopic Investigation of Light Strange S=-1 $Λ$, $Σ$ and S=-2 $Ξ$ Baryons

Published 1 Apr 2021 in hep-ph | (2104.00439v1)

Abstract: The present study is dedicated to light-strange $\Lambda$ with strangeness S=-1, isospin I=0; $\Sigma$ with S=-1, I=1 and $\Xi$ baryon with S=-2 and $I=\frac{1}{2}$. 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 $(n,M{2})$ and $(J,M{2})$ respectively. Magnetic moments have been intensively studied for ground state spin $\frac{1}{2}$ and $\frac{3}{2}$, in addition to the configuration mixing for first negative parity state for $\Xi$. Lastly, transition magnetic moment and radiative decay width have been presented.
