Findings

Predicted ground state masses for $\\Xi$ and $\\Omega$ baryons.

Estimated excited state masses in $(J,M^{2})$ and $(n,M^{2})$ planes.

Predicted spin-parity assignments for recently observed baryons.

Abstract

The present article contains the descriptive study of light strange baryons $\Lambda$, $\Sigma$, $\Xi$, and $\Omega$. The Regge phenomenology with quasi-linear Regge trajectories has been employed and the relations between Regge slopes, intercepts, and baryon masses have been extracted. With the aid of these relations, ground state masses are obtained for $\Xi$ and $\Omega$ baryons. Further, the Regge parameters have also been estimated to calculate the excited state masses for $\Lambda$, $\Sigma$, $\Xi$, and $\Omega$ baryons in both the $(J,M^{2})$ and $(n,M^{2})$ planes. The obtained results are compared with available experimental data and various theoretical approaches. The spin-parity of recently observed light baryons are predicted in this work and our predictions may be useful in future experimental searches of these baryons and their $J^{P}$ assignments.
