TL;DR
This paper reviews how dynamical chiral symmetry breaking and confinement in Quantum Chromodynamics explain the origin of most of the visible universe's mass, using the Schwinger-Dyson equations as a key tool.
Contribution
It provides an introductory overview of the role of chiral symmetry breaking and confinement in mass generation within QCD, emphasizing the Schwinger-Dyson equations approach.
Findings
Chiral symmetry breaking accounts for 98% of visible mass.
Confinement is essential for understanding hadron spectrum.
Schwinger-Dyson equations are effective in studying these phenomena.
Abstract
Dynamical chiral symmetry breaking and confinement are two crucial features of Quantum Chromodynamics responsible for the nature of the hadron spectrum. These phenomena, presumably coincidental, can account for 98% of the mass of our visible universe. In this set of lectures, I shall present an introductory review of them in the light of the Schwinger-Dyson equations.
