Contribution

It introduces a detailed analysis of diquark correlations within baryons using the Schwinger functional method, advancing understanding of hadron mass generation and internal structure.

Findings

Dynamical gluon mass generation is confirmed in Landau gauge.

Diquark correlations significantly influence baryon masses and structure.

Electromagnetic form factors reveal the quark-diquark composition of baryons.

Abstract

This conference proceedings contribution emphasizes the emergent hadron mass paradigm, which accounts for the majority of the visible mass in the universe, beyond the Higgs boson mechanism. The study delves into the Landau gauge gluon propagator and the dynamical generation of gluon mass, as well as the dressed-quark propagator and dynamical chiral symmetry breaking. It also tackles the baryon bound state problem through the Poincar\'e-covariant Faddeev equation, analyzing the composition and masses of octet and decuplet baryons. The document concludes with a discussion on the electromagnetic form factors of the nucleon and its first radial excitation, providing insights into the quark-diquark structure within baryons.
