Cosmic neutrinos at IceCube: θ13\theta_{13}, δ\delta and initial flavor composition

Abstract

We discuss the prospect of extracting the values of the mixing parameters δ\delta and θ13\theta_{13} through the detection of cosmic neutrinos in the planned and forthcoming neutrino telescopes. We take the ratio of the muon-track to shower-like events, R, as the realistic quantity that can be measured in the neutrino telescopes. We take into account several sources of uncertainties that enter the analysis. We then examine to what extent the deviation of the initial flavor composition from w_e:w_\mu:w_\tau=1:2:0 can be tested.Comment: 3 pages, 2 figures, Talk given at the TAUP 2009 conference, Rome, Italy; J.
