Abstract

The final results of the MACRO experiment on atmospheric neutrino oscillations are presented and discussed. The data concern different event topologies with average neutrino energies of similar to3 and similar to50 GeV Multiple Coulomb scattering of the high-energy muons in absorbers was used to estimate the neutrino energy of each event. The angular distributions, the L/E-v distribution, the particle ratios, and the absolute fluxes all favor v(mu) --> v(tau) oscillations with maximal mixing and Deltam(2) = 0.0023 eV(2). A discussion is made on the Monte Carlos used for the atmospheric neutrino flux. Some results on neutrino astrophysics are also briefly discussed. (C) 2004 MAIK "Nauka/Interperiodica".
