Neutrino Flavor as a Marker of the Phase Structure of the Cyclic Universe in the PSP Model

This paper presents an analysis of the flavor composition of the neutrino flux from the ICECAT-1 catalog (275 events, 2011-2020) within the framework of the Phase State Parameter (PSP) cosmological model. It is shown that electron neutrinos dominate the flux (72.4%), while tau neutrinos constitute only 4.4%. A correlation is found between neutrino flavor and spatial distribution relative to the PSP phase zones: in the ring zone (M = 0.25-0.35), the fraction of ν_e is 71.2%, while ν_tau are practically absent (1.9%). The results indicate a connection between neutrino flavor and the phase structure of the cycle, confirming the PSP model as an alternative to the standard cosmological model. Neutrino flavor can serve as an effective marker of the phase structure of the Universe.
