Neutrinos in Strmšek projection theory (SPT)

Introduction Neutrino physics continues to expose fundamental gaps in our theoretical understanding. The observation of flavor oscillations established that neutrinos have nonzero masses, yet their absolute scale and mixing structure remain without explanation. In the Standard Model, these phenomena are accommodated by the empirical PMNS matrix, which provides an accurate fit to data but no account of why its parameters take the observed values. The Strmšek Projection Theory (SPT) addresses this problem by embedding neutrino properties in higher-dimensional geometry. Within SPT, neutrinos are realized as phase-incomplete projections of toroidal modes in an extended dimensional space (formally defined in Sec.~2). Oscillations emerge from interference of projection phases. Effective masses appear as residual energies left by incomplete projection, and weak interactions result from near-cancellation of conjugate modes. In this way, SPT not only reproduces established neutrino phenomenology but also advances clear, testable predictions. It anticipates systematic deviations at the level of 1–2% in survival probabilities and an effective neutrino number of . These values will be directly probed by upcoming facilities, including JUNO~\cite{JUNO_TDR}, IceCube-Gen2~\cite{IceCubeGen2_WhitePaper}, and CMB-S4~\cite{CMBS4_ScienceBook}. By connecting neutrino properties to geometric projection principles, SPT offers a falsifiable alternative to purely empirical parametrizations. Contact: [email protected]
