Weak interactions constitute one of the four fundamental interactions of nature and play a central role in particle transformations, beta decay, neutrino physics, and flavor-changing processes. Within the Standard Model, weak interactions are described by the electroweak gauge theory based on the symmetry group SU(2)u2097 × U(1)ᵧ and are mediated by the massive W and Z bosons. Although this framework has achieved remarkable experimental success, several fundamental questions remain unresolved, including the physical origin of flavor transitions, the nature of weak bosons, the origin of mixing matrices, and the connection between weak interactions and the underlying structure of spacetime. Unified Fractal Quantum Field Theory (UFQFT) proposes an alternative interpretation in which weak interactions emerge from resonance transformations occurring within coupled energy (Φ) and charge (Ψ) fields embedded in a critical fractal spacetime characterized by an effective dimension near D ≈ 2.7. In this framework, particles are not regarded as fundamental objects but as stable resonance configurations, and weak processes correspond to transitions between resonance states. The transformation of up and down quark resonances, beta decay, flavor mixing, and weak-boson phenomena are interpreted as manifestations of resonance evolution rather than fundamental gauge-mediated interactions. In this work, we develop a systematic formulation of weak interactions within UFQFT and compare it with the Standard Model description. The resonance transformation mechanism is applied to neutron beta decay, charged-current and neutral-current processes, flavor mixing, and weak decay phenomena. Theoretical predictions are compared with experimental observations including neutron lifetime measurements, weak decay rates, and precision electroweak data. We further investigate whether the effective gauge structure of the Standard Model may emerge as a low-energy approximation of a deeper resonance-geometric framework. The results suggest that weak interactions can be consistently interpreted as resonance transformations while preserving the observed conservation laws and phenomenological behavior of known weak processes. This study represents a key component of the UFQFT Standard Model Validation Program and provides a foundation for subsequent investigations of neutrino oscillations, CP violation, and matter—antimatter asymmetry within a unified resonance-based framework.
