Quark Confinement: A Baryon Confinement Theory Presentation

This presentation discusses a framework for a baryon confinement theory and addresses long-standing questions about quark confinement in quantum chromodynamics (QCD). It explores the Dirac equation for composite baryon quarks, flavors and generations, baryon mass spectrum calculations, and the possibility of a calculable theory in the confinement range. The presentation also proposes a mechanism for chiral symmetry breaking and explores the connection between flavor states and mass gain in quarks. The calculations of the strong running coupling constant and baryon mass spectra are also discussed.

  26. Lowest Order Multipole Color Fields 26 Theoretical Framework

  27. 27 Abstract Dirac equation is solved for 3 massless quarks under influence of generated color fields. If quarks and gluons have identical velocities, then chiral symmetry is broken. Color electric field is totally cancelled; quarks are trapped in color magnetic bottle; gluons are trapped by circulating quarks in quantized color magnetic flux bundles. Second quantization and Hartree approach are used to solve Dirac equation. Each quark along with its bundle of gluons behaves as a composite particle with mass gained from symmetry breaking. Solution exhibits a series of degenerate ground states that give rise to quark flavor states. Spinor wave function solutions from Dirac equation are used to calculate baryon mass spectrum.
