Abstract

We have previously shown that the decay of high-energy neutrinos from distant astrophysical sources would be revealed by flavor ratios that deviate strongly from the \ensuremathφ_\ensuremathν_e:\ensuremathφ_\ensuremathν_\ensuremathμ:\ensuremathφ_\ensuremathν_\ensuremathτ=1:1:1 expected from oscillations alone. Here we show that the deviations are significantly larger when the mixing angle \ensuremathθ₁₃ and the CP phase \ensuremathδ are allowed to be nonzero. If neutrinos decay, this could allow measurement of \ensuremathθ₁₃ and \ensuremathδ in IceCube and other near-term neutrino telescopes.
