A 3-D Calculation of Atmospheric Neutrino Fluxes

We present a fully three-dimensional calculation of atmospheric neutrino fluxes using accurate models of the geomagnetic field, hadronic interactions, tracking and decays. Results are presented for the Super-Kamiokande (SK) and Sudbury Neutrino Observatory (SNO) sites. We discuss departures from previous 1-D calculations, particularly with regard to overall fluxes, east-west asymmetries, and the recently reported geometrical enhancement of low energy, horizontal neutrinos.
