Primordial Genesis in a Zero-Spin Vacuum Bouncing Cosmology

This metadata entry record constitutes the fourth, concluding installment of a foundational cosmological paper tetralogy (complementing the preceding works registered under DOI:10.5281/zenodo.22763071, DOI:10.5281/zenodo.23153625, and DOI:10.5281/zenodo.23209528). In this final paper, we formalize the self-consistent microphysical scenarios and underlying relativistic field equations governing primordial lepto- and baryogenesis within a strictly deterministic, parameter-free Extremal Quantum Black Hole (EQBH) cosmological bounce framework occurring immediately post-turnaround. Operating within the rigid geometric boundaries of an effective N=1 supergravity (SUGRA) action and a q-deformed U_q(su(2)) horizon algebra, we trace the top-down reverse-engineering map from Planck-scale remnants to Standard Model matter fields without invoking highly tuned auxiliary fields or unconstrained post-bounce inflation boundaries. Crucially, this work resolves the long-standing flavor puzzle within the ansatz by introducing a top-down, two-stage Inverse Spin-Seesaw cascade for the charged lepton sector. We demonstrate that below the Riemann-regularized zero-spin vacuum threshold (M_crit ≈ 0.5601 M_P), where both the asymptotic selectron and electron states obey the unshifted Casimir spin-algebraic relation, the discrete spin mismatch (ΔJ = √3/2) structurally locks the effective Yukawa coupling. This mechanism dynamically projects the heavy Planck-scale scalar selectron mass gap (M_e ≈ 0.002584 M_P) down to the Standard Model electron mass scale (m_e ≈ 0.511 MeV) via a single low-energy electroweak parameter (v_EW = 246.22 GeV), completely stripping the low-energy lepton flavor sector of arbitrary, adjustable inputs. Concurrently, the paper maps out:1. Unified Lepto- and Baryogenesis Dynamics: Tracing the sub-Planckian three-body beta decays of dark-sector super-neutrons that seed the primary lepton background and active neutrino mass scales (m_nu_a ≈ 0.05 eV, m_nu_s ≈ 0.009 eV), paired with a laser-driven CP-violation mechanism that secures the observed baryon asymmetry.2. Dual-Component Super-Atomic Dark Matter: Formalizing the freeze-out of unreacted sub-Planckian defects into single-charge ionic [M_0,0 x e]^- configurations regulated by an internal Coulomb blockade, and saturated neutral [M_0,0 x Nν] sneutrino super-atoms bounded by the strict Kaup-Ruffini-Bonazzola mass limit (M_max ≈ 0.29 g). This multi-component partitioning naturally resolves the empirical dark sector allocations (Ω_Λ ≈ 68.3%, Ω_c ≈ 26.9%).3. Definitive Empirical Signatures: Providing explicit mappings onto next-generation polarization surveys, including a monochromatic microwave laser chirp (ν_now ≈ 1.5 GHz) that naturally matches the ARCADE 2 cosmic radio excess, and a sub-kilohertz wide-bandwidth stochastic gravitational wave noise background centered at 310.3 Hz. As the definitive structural synthesis of the entire tetralogy, this concluding work establishes a unified cosmological paradigm that is fundamentally parameter-free, independent of localized baryon asymmetry signs, and structurally renormalizable across varying deep ultraviolet scales.
