The Zepto-Scale Thermodynamic Cascade: Empirical Validation of Fractional Scaling via Rare Bº Meson Decay

Recent observations by the CERN LHCb experiment revealing exceptionally rare neutral Bº meson decay present critical empirical evidence for physics beyond the Standard Model at the 10^-21 meter scale (the "zeptoverse"). This paper posits that these subatomic anomalies are the direct observable consequence of a Thermodynamic Cascade—an infinite, scale-variant fractal structure where entropic gradients drive energy downward into fractional dimensional states. By applying microscopic calibrations of the dimensional transition constant (Λ) and the effective fractional dimension (D), this paper provides the mathematical framework demonstrating that scale-variant entropic gravity governs these rare transformations without reliance on holographic projections or simulated realities.
