Comprehensive Measurement of the Reactor Antineutrino Spectrum
Year: 2025
Type: article
Abstract: This paper demonstrates that the anomalies observed in reactor antineutrino spectra— including the 5–7% flux deficit and the “5 MeV bump” reported by the DayaBay Collaboration (2025) — emerge naturally from the temporal coherence dynamicsof the Universal Lagrangian. The framework predicts that time–dependent phasegradients in nuclear domains lead to oscillatory corrections in the emitted antineutrinoflux, without the need for sterile neutrinos or ad–hoc nuclear models. The derivedexpression for the spectral deformation reproduces both the amplitude and shape ofthe experimental data within the reported uncertainty.The experimental reference for the present theoretical analysis is the comprehensivemeasurement of the reactor antineutrino spectrum and flux performed by the DayaBay Collaboration (2025) [1].A direct experimental validation of this theoretical framework is discussed in AppendixE, where the reactor antineutrino flux anomalies observed by the Daya BayCollaboration (2025) [1] are quantitatively reproduced by the same temporal coherencedynamics of the field.
