Mass-spectra of singly, doubly, and triply bottom baryons

TL;DR

This paper calculates the ground and excited state masses of bottom baryons using Regge phenomenology, aiding in the identification of their quantum numbers and supporting future experimental efforts.

Contribution

It introduces a novel application of Regge phenomenology to predict masses and quantum numbers of bottom baryons, including excited states and spin-parity assignments.

Findings

Calculated masses agree with experimental data where available.

Estimated Regge slopes and intercepts for bottom baryons.

Provided predictions for unobserved excited states.

Abstract

The present work has been done on the baryons containing one, two, or three bottom quarks. In this article, the ground-state masses of $\Omega_{b}^{-}$, $\Xi_{bb}^{0}$, $\Xi_{bb}^{-}$, $\Omega_{bb}^{-}$, and $\Omega_{bbb}^{*-}$ baryons are calculated within the framework of Regge phenomenology. Further, the values of Regge slopes and Regge intercepts for singly, doubly, and triply bottom baryons are estimated in both the ($J,M^{2}$) and ($n,M^{2}$) planes to calculate the excited-state masses of these baryons. Here our attempt is to assign a possible spin-parity to recently observed some singly bottom baryons and our results could provide useful information for future experimental searches. Our calculated masses are in agreement with the experimental observations where available and close to other theoretical predictions.
