The Leptonic Mode: The Electron as Resonance of the Minority-Mass Endpoint (XV v4)

This paper develops the second sub-hadronic hypothesis of the FCD-RBv4 (Folded Crunch Dipole – Reversed Big Bang) framework, establishing that the electron is not an independent fundamental field, but the inseparable leptonic resonance of the minority-mass endpoint of the quark Einstein-Rosen (ER) dipole. First, we demonstrate that the fractional quark charges +2/3 e and −1/3 e are the unique, mathematically compelled solutions to the baryonic integercharge constraints (2x+y = 1 for the proton and x+2y = 0 for the neutron) given a three-dipole anchor. We then formulate the Triplet Cancellation Rule, explaining how the two minority-mass endpoints of a proton (AAB) cancel their helical phase-windings at the common anchor point, projecting exactly one effective leptonic mode (the electron) with net charge −e and spin-1/2. The neutron’s (ABB) magnetic moment, historically underestimated at −1.333 µ N under a static approximation, is corrected toward the experimental value of −1.913 µ N by deriving a subcritical residual phase resonance (ε B ≈ 0.10) at Mode-B endpoints. Finally, we reinterpret beta decay ¯νe (n → p + e − + ) as a local mode redistribution (B → A) within a single dipole, identifying the antineutrino as a topological bulk echo, and outline how the atomic shell structure and the Pauli Exclusion Principle emerge directly from the boundary conditions of the nuclear leptonic network.
