Contribution
It introduces a formalism for an interacting quark-diquark model and applies it to compute baryon spectra and observables, providing a comprehensive approach.
Findings
Accurately reproduces strange and nonstrange baryon spectra
Calculates baryon magnetic moments and decay widths
Incorporates self-energy corrections for baryon masses
Abstract
We describe the relativistic interacting quark-diquark model formalism and its application to the calculation of strange and nonstrange baryon spectra. The results are compared to the existing experimental data. We also discuss the application of the model to the calculation of other baryon observables, like baryon magnetic moments, open-flavor strong decays and baryon masses with self-energy corrections.
