The authors' main claim 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.

The compiled record

The paper's own sentences, arranged. Each label is drawn from a closed vocabulary; the number beside it is the probability the classifier gave that label. Numbers in the tables are the authors', checked by code. No sentence in this record was written by a model.

The abstract, sentence by sentence

arXiv listing abstract v1. Results and the main claim are underlined; .

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.

Original 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.
