Multi-Year Search For A Diffuse Flux Of Muon Neutrinos With Amanda-Ii

A search for TeV to PeV muon neutrinos from unresolved sources was performed on AMANDA-II data collected between 2000 to 2003. The diffuse analysis sought to identify an extraterrestrial neutrino signal on top of the atmospheric muon and neutrino backgrounds. An upper limit of E-2 Phi(90%C.L.) < 8.8 x 10(-8) GeV cm(-2) s(-1) sr(-1) was placed on the diffuse flux of muon neutrinos with a dN/dE similar to E-2 spectrum for the energy range 15.8 TeV to 2.5 PeV. Limits were also placed on prompt and astrophysical neutrino models with other energy spectra.
