Particle Production, Helicity Asymmetry, and Baryogenesis in a Dust-Dominated Loop Quantum Cosmology Bounce: A Numerical Study
Year: 2026
Type: article
Abstract: This working paper presents a computational study of particle production during a dust-dominated Loop Quantum Cosmology (LQC) bounce. MAIN RESULTS:- Wronskian verification at the 10^-9 level- Scalar spectrum peaks at k ≈ 0.7- Fermion helicity Δn_k flips sign at k ≈ 1- Baryon asymmetry η_B ≈ 6 × 10^-10 COMPARISON WITH OBSERVATION:- η_B matches Planck+BBN within 2%- n_s ≈ 1.04 vs Planck 0.9649 NOVEL FINDING — SPECTRAL STRUCTURE:Delta n_k decomposes into 4 cosine components with geometrically spaced frequencies: ω_j = ω_0 × (√2)^(j-1)Bootstrap estimate: r = 1.4221 ± 0.0264Comparison with √2: 0.297σ NEGATIVE RESULTS:- Kernel z(θ) hypothesis rejected (4 independent tests)- Particle family hypothesis rejected SCOPE AND CAUTION:This is a methodological working paper, not a physics discovery paper. The efficiency factor κ is a free parameter (consistency check, not prediction). No full CMB analysis (CAMB, MCMC) is performed. The √2 structure is a numerical observation whose physical origin remains unexplained.
