“…The IceCube collaboration presented evidence of this astrophysical neutrino flux just two years ago, at International Cosmic Ray Conference (ICRC) 2013 in Rio de Janeiro [7]. The measured neutrino flux level is close to the theoretical upper bound inferred from the ultra-high-energy cosmic ray (UHECR) flux measurements [8].…”

This report is the write-up of a rapporteur talk on neutrino astronomy given at the 34th International Cosmic Ray Conference in The Hague, Netherlands, in 2015. Here, selected contributions on the neutrino astronomy from the total of 40 talks and 90 posters presented in NU sessions at the 34th ICRC are summarized in the attempt of providing a status report on this rapidly glowing new field. The field of neutrino astronomy has recently experienced a "phase transition" since the first observation of high energy cosmic neutrinos. Extensive efforts have been made to identify the origin of the neutrino flux observed in the 100 TeV to PeV region, from both theoretical and experimental perspectives. In addition, the search for neutrino fluxes beyond the observed level has become increasingly important for further understanding the origin of the observed cosmic-ray up to 10 20 eV. Although the IceCube Neutrino Observatory is the only experiment currently measuring this neutrino flux, its initial measurements have been confirmed via analysis using several independent detection channels. Further, there have been a number of developments in the search for neutrino point sources, while no successful observations have yet been reported. Following the IceCube observations, a large number of studies of next-generation neutrino detectors, including up-scaled underground Cherenkov neutrino detectors and Cherenkov radio neutrino detectors, have been reported.

“…It is also worth to note that despite corrections from the neutrino effective areas and the atmospheric muon backgrounds, technically translating an event topology to the interacting flavor neutrinos involves complicated analyses. For example, the High Energy Starting Events (HESE) method[62,63] requires the entering particles being energetic enough and is used to select neutrino-like events by vetoing low energy events in which the earliest light is observed in the outer part of the detector. The complication of such analysis could induce further uncertainty for measuring neutrino fluxes and thus affect the value of flavor composition T .…”

Constraining astrophysical neutrino flavor composition from leptonic unitarity

The recent IceCube observation of ultra-high-energy astrophysical neutrinos has begun the era of neutrino astronomy. In this work, using the unitarity of leptonic mixing matrix, we derive nontrivial unitarity constraints on the flavor composition of astrophysical neutrinos detected by IceCube. Applying leptonic unitarity triangles, we deduce these unitarity bounds from geometrical conditions, such as triangular inequalities. These new bounds generally hold for three flavor neutrinos, and are independent of any experimental input or the pattern of leptonic mixing. We apply our unitarity bounds to derive general constraints on the flavor compositions for three types of astrophysical neutrino sources (and their general mixture), and compare them with the IceCube measurements. Furthermore, we prove that for any sources without ν τ neutrinos, a detected ν µ flux ratio < 1/4 will require the initial flavor composition with more ν e neutrinos than ν µ neutrinos.
