26 Theoretical Framework • Lowest Order Multipole Color Fields

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. 27
