Reinterpreting Beta Decay and Weak Interaction Background Information Recovery within Existence-Quantized Geometric Theory

The weak interaction is conventionally treated as a fundamental force responsible for beta decay, electron capture, and particle transmutation, typically described through force carriers, coupling constants, and probabilistic decay rates. This paper presents a structural reinterpretation of beta decay and weak interaction within the framework of Existence-Quantized Geometric Theory (EQGT). Rather than acting as an independent force, weak interaction phenomena are modeled as background information recovery processes, in which information particles are redistributed from over-compressed local structures back into the global background to maintain structural equilibrium. Within this framework, beta decay and electron capture are understood as role-switching processes of information particles, involving transitions between internal, boundary-condition, and emission-side roles. Apparent probabilistic behavior and decay lifetimes are reinterpreted as observer-facing manifestations of underlying structural conditions, including compression excess, boundary regulation capacity, and background information pressure gradients. This role-based recovery model unifies weak interaction phenomena with nuclear stability, mass defect reinterpretation, and cosmological background constraints, while preserving existing weak-interaction formalisms as effective descriptions within observer-limited regimes rather than as fundamental forces.
