Paper 47:Spatial Quantum Phase Transition and Baryon Asymmetry: Asymmetric Decay Mechanism in the Huaxia Spacetime Total Conservation Theory

The observed universe contains virtually no primordial antimatter, yet the Standard Model cannot quantitatively explain the baryon asymmetry. This paper proposes a novel mechanism within the H-SET framework: during the spatial condensation phase of the extremely early universe, equal numbers of vortex rings and anti-vortex rings are produced, but the fixed helicity selectivity of the chiral torsion field causes the decay rate of anti-vortex rings to be far higher than that of their matter counterparts. Based on the Basal Elastic Mass Invariance Theorem and a chiral asymmetry parameter constrained by the lepton mass spectrum, we derive the asymmetric decay dynamics. After production ceases, anti-vortex rings decay back into diffuse space on a timescale far shorter than the Hubble time, while vortex rings remain stable, becoming the source of all matter in the observable universe. The final baryon-to-photon ratio naturally reaches the order of ten to the minus ten, consistent with observations, without introducing new physics beyond the established H-SET axioms.
