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

\phi_{\nu_e}:\phi_{\nu_\mu}:\phi_{\nu_\tau} = 1:1:1

expected from oscillations alone. Here we show that the deviations are significantly larger when the mixing angle

\theta_{13}

and the CP phase

\delta

are allowed to be nonzero. If neutrinos decay, this could allow measurement of

\theta_{13}

and

\delta

in IceCube and other near-term neutrino telescopes.
