Determination of the masses and decay widths of the well-established $s$ and $p$ baryon resonances below $2$ GeV

TL;DR

This paper estimates the masses and decay widths of well-established $s$ and $p$ baryon resonances below 2 GeV using recent Particle Data Group data, focusing on $N$ and $$ states with specific strangeness and isospin.

Contribution

It provides updated estimates for baryon resonance properties based solely on recent experimental data, refining previous knowledge.

Findings

Masses and decay widths of $s$ and $p$ baryon resonances are quantified.

Results focus on $N$ and $$ states with specific quantum numbers.

Data derived exclusively from Particle Data Group compilation.

Abstract

This study appertains to the extraction of estimates for the masses and for the partial decay widths to pion-nucleon final states of the well-established (four-star) $s$ and $p$ baryon resonances below $2$ GeV. These estimates are exclusively obtained from the data contained in the recent compilation by the Particle Data Group. Only the $N$ ($S=0,I=1/2$) and the $\Delta$ ($S=0,I=3/2$) states are considered, where $S$ and $I$ denote strangeness and total isospin, respectively.
