摘要

We present the expected baseline sensitivity of the IceCube detector to cosmogenic neutrinos producedthrough the GZK process. Data from the partially completed IceCube detector have previously been searched for suchhighly energetic ( u0015 106 GeV) neutrinos. With the completion of the detector in December 2010 and the full operationhaving started in May 2011, IceCube's sensitivity to these neutrinos is significantly improved from previous studies. Wecalculate the expected sensitivity in the search of cosmogenic (GZK) neutrinos using a Monte Carlo simulation of thecompleted IceCube detector and the selection criteria developed in the previous analysis. The sensitivity for a diffuseflux of cosmic neutrinos with an E2 spectrum in the central 90% energy range 300 TeV to 2 EeV is expected to be at alevel of E2°u0017 e +u0017 +u0017 u0014 1.3 × 108GeVcm2sec1sr1 with one year of operation. The corresponding differential sensitivity is also presented.
