Spectroscopy of singly, doubly, and triply bottom baryons

TL;DR

This paper uses Regge phenomenology to predict the masses of unobserved doubly and triply bottom baryons based on known baryon masses, aiding future experimental discovery and quantum number assignment.

Contribution

It introduces a method to estimate masses of unobserved bottom baryons using Regge trajectories, extending predictions to doubly and triply bottom states.

Findings

Calculated Regge slopes and intercepts for bottom baryons.

Estimated masses of orbitally excited bottom baryons.

Provided predictions to guide experimental searches.

Abstract

Recently, some singly bottom baryons have been established experimentally, but none of doubly or triply bottom baryons has been observed. Under the Regge phenomenology, the mass of a ground state unobserved doubly or triply bottom baryon is expressed as a function of masses of the well established light baryons and singly bottom baryons. Then, the values of Regge slopes and Regge intercepts for baryons containing one, two, or three bottom quarks are calculated. After that, masses of the orbitally excited singly, doubly, and triply bottom baryons are estimated. Our predictions may be useful for the discovery of these baryons and the $J^P$ assignment of them.
