- A search for diffuse neutrinos with energies in excess of 105 GeV is conducted with AMANDA-II data recordedbetween 2000 and 2002. Above 107 GeV, the Earth is essentially opaque to neutrinos. This fact, combined with thelimited overburden of the AMANDA-II detector (roughly 1.5 km), concentrates these ultraYhigh-energy neutrinos atthe horizon. The primary background for this analysis is bundles of downgoing, high-energymuons fromthe interactionof cosmic rays in the atmosphere. No statistically significant excess above the expected background is seen in the data,and an upper limit is set on the diffuse all-flavor neutrino flux of E290%CL < 2:7 ; 107 GeV cm2 s1 sr1 valid overthe energy range of 2 ; 105 to 109 GeV. A number of models that predict neutrino fluxes from active galactic nucleiare excluded at the 90% confidence level.
