Flavor Ratios and Mass Hierarchy at Neutrino Telescopes
The observation of high-energy extraterrestrial neutrinos at IceCube represents the beginning of the era of neutrino astronomy. In this paper, we study the cosmic neutrino flavor ratios against the
Open issues in neutrino astrophysics
Neutrinos of astrophysical origin are messengers produced in stars, in explosive phenomena like core-collapse supernovae, in the accretion disks around black holes, or in the Earth's atmosphere.
Cosmic neutrino flavor ratios with broken ν μ-ν τ symmetry
Abstract Reactor neutrino experiments have now observed a nonzero value for θ 13 at 5 σ , and global fits to data imply a nonzero value above 10 σ . Nonzero values for θ 13 and/or θ 32 − π 4 break a
A flavored model of astrophysical neutrinos in IceCube
We fit the energy distribution of the IceCube starting events by a model which involves four parameters in the neutrino spectrum, namely three normalizations $n_e,n_\mu,n_\tau$ and a common power-law

Nonstandard interaction effects on astrophysical neutrino fluxes
We investigate new physics effects in the production and detection of high-energy neutrinos at neutrino telescopes. Analyzing the flavor ratios ϕμ/ϕτ and ϕμ/(ϕτ+ϕe), we find that the standard model
Conflict between the identification of a cosmic neutrino source and the sensitivity to mixing angles in a neutrino telescope
Neutrino fluxes at telescopes depend on both initial fluxes out of astronomical bursts and flavor mixing during their travel to the Earth. However, since the information on the initial composition
Flavor Composition and Energy Spectrum of Astrophysical Neutrinos
The measurement of the flavor composition of the neutrino fluxes from astrophysical sources has been proposed as a method to study not only the nature of their emission mechanisms, but also the
Implications of leptonic unitarity violation at neutrino telescopes
A measurement of the ultrahigh-energy (UHE) cosmic neutrinos at a km(3)-size neutrino telescope will open a new window to constrain the 3 x 3 neutrino mixing matrix V and probe possible new physics.
Confusing sterile neutrinos with deviation from tribimaximal mixing at neutrino telescopes
We expound on the impact of extra sterile species on the ultra high energy neutrino fluxes in neutrino telescopes. We use three types of well-known flux ratios and compare the values of these flux
Testing neutrino flavor mixing plus decay with neutrino telescopes
We discuss the interplay of neutrino oscillation and decay properties at neutrino telescopes. Motivated by recent unparticle scenarios, which open the possibility of new neutrino decay modes over
An analysis of cosmic neutrinos: Flavor composition at source and neutrino mixing parameters
Abstract We examine the feasibility of deriving neutrino mixing parameters δ and θ 13 from the cosmic neutrino flavor composition under the assumption that the flavor ratios of the cosmic neutrinos
Interplay of energy dependent astrophysical neutrino flavor ratios and new physics effects
We discuss the importance of flavor ratio measurements in neutrino telescopes, such as by measuring the ratio between muon tracks to cascades, for the purpose of extracting new physics signals
On probing theta23 in neutrino telescopes
Among all neutrino mixing parameters, the atmospheric neutrino mixing angle theta_{23} introduces the strongest variation on the flux ratios of ultra high energy neutrinos. We investigate the
Global status of neutrino oscillation parameters after Neutrino-2012
Here we update the global fit of neutrino oscillations in arXiv:1103.0734 and arXiv:1108.1376 including the recent measurements of reactor antineutrino disappearance reported by the Double Chooz,
