Excited hyperons of the $N = 2$ band in the $1/N_c$ expansion

TL;DR

This paper reanalyzes the spectrum of excited baryons in the N=2 band, focusing on hyperons, using the 1/Nc expansion method to classify them into SU(3) multiplets and make predictions.

Contribution

It applies the 1/Nc expansion to classify N=2 band hyperons into SU(3) multiplets and provides new predictions for their spectrum.

Findings

Hyperons classified into SU(3) singlets, octets, and decuplets.

Predictions for masses and quantum numbers of excited hyperons.

Enhanced understanding of baryon structure in the 1/Nc framework.

Abstract

The spectrum of excited baryons in the $N$ = 2 band is reanalys9 pagesed in the $1/N_c$ expansion method, with emphasis on hyperons. Predictions are made for the classification of these excited baryons into SU(3) singlets, octets and decuplets.
