Relativistic quark-diquark model of baryons with a spin-isospin transition interaction

TL;DR

This paper extends a relativistic quark-diquark model of baryons by adding a spin-isospin transition interaction, enabling more accurate calculations of the non-strange baryon spectrum and comparison with experimental data.

Contribution

The paper introduces a novel spin-isospin transition interaction into the relativistic quark-diquark model of baryons, enhancing its predictive power.

Findings

Improved baryon spectrum calculations

Better agreement with experimental data

Validation of the extended model

Abstract

The relativistic interacting quark-diquark model of baryons, recently developed, is here extended to introduce a spin-isospin transition interaction into the mass operator. The refined version of the model is used to calculate the non strange baryon spectrum. The results are compared to the present experimental data.
