THEORETICAL MODEL OF NEUTRON HALF-LIFE BASED ON COSMOPHYSICAL FLUX DYNAMICS

We present a theoretical model linking neutron decay to high-energy solar neutrino flux, predicting a neutron half-life of T1/2=610.54 with corresponding mean lifetime (τ) of τ=880.83±20.81 seconds. Here, the uncertainty is not statistical but a systematic seasonal deviation caused by Earth’s changing distance from the Sun, which alters the density of neutrinos reaching Earth. The ±3.34% annual variation in solar neutrino flux (due to Earth’s ±1.67% orbital eccentricity) corresponds to a half-life range of τ∈[852.13 s, 911.08 s].
