Baryon Asymmetry from First Principles: A Parameter-Free Derivation of ηB

Key Points

• To derive the baryon-to-photon ratio η_B from a parameter-free framework using a master equation.
• Derivation of η_B from a single master equation with zero free parameters.
• Comparison of derived ratio with Planck 2018 observations.
• Provision of four falsifiable predictions.
• Derived η_B = 6.15×10⁻¹⁰, agreeing with Planck 2018 value of 6.12×10⁻¹⁰ to 0.49% accuracy.
• The derivation is parameter-free, enhancing its predictive power.
• Four distinct predictions established for future verification.
