Abstract

This research establishes a spectral-geometric framework to address the persistent tension in the muon anomalous magnetic moment (a_). Departing from traditional perturbative QED approaches, we derive the correction to a_ from the operator-theoretic structure of the vacuum, specifically utilizing the heat kernel expansion of a Dirac-type operator defined on a gauge-invariant geometric structure. The model provides a rigorous mathematical origin for both ultraviolet (UV) -suppressed contributions and infrared (IR) -enhanced mechanisms mediated by topological zero-modes. Crucially, the framework generates a hierarchy of falsifiable signatures—including multipole field correlations, beam-profile dependencies, and azimuthal modulations—that are experimentally testable in current and future storage ring facilities. This work offers an alternative theoretical perspective on the g-2 anomaly, emphasizing the fundamental spectral geometry of the vacuum over standard model phenomenological fitting.
