Theoretical results for hadronic masses and their widths in the framework of the SO(4) model

TL;DR

This paper explores the SO(4) model's effectiveness in predicting low-energy hadronic spectrum properties, including masses and widths, by comparing theoretical calculations with experimental data.

Contribution

It introduces the SO(4) scheme as a framework for modeling meson-like states and systematically compares its predictions to experimental results.

Findings

SO(4) model provides reasonable predictions for hadronic masses and widths

Theoretical results show good agreement with experimental data below 2.5 GeV

The model captures key features of the low-energy hadronic spectrum

Abstract

The prediction of properties of the low energy portion of the hadronic spectrum is a challenging task which, up to day, is still tentatively given due to the non-perturbative nature of QCD at low energies. In this paper we are exploring the validity of the SO(4) scheme, as representative of the fundamental QCD structure of meson-like states in the region below 2.5 GeV. We have focussed the attention in the calculation of the energy and width of states of various spin, isospin and parities. The theoretical results are compared, sistematically, to the available experimental information.
