Conflict between the identification of cosmic neutrino source and the sensitivity to mixing angles in 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 requires better precision in mixing angles and vice versa, the neutrino detection at telescopes for itself cannot provide solutions to the both problems. Thus, a probability to be measured at long baseline oscillation is considered as a complement to the telescope, and problems like source identification and parameter degeneracy are examined under a few assumptions.Comment: 17 pages with 7 figures, published versio
