2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/202562Aspects of neutrino physics beyond the Standard Model are emphasized, including the emerging default options for atmospheric and solar neutrino oscillations, namely nu_mu to nu_tau and nu_e to nu_{mu,tau} respectively, and the need to check them, the prospects opened up by the successful starts of SNO and K2K, the opportunities for future long-baseline neutrino experiments and high-energy astrophysical neutrinos. Finally, comments are made on the road map for realizing the exciting physics potential of neutrino factories.15 pages, 12 eps figures, uses espcrc2.styHigh Energy Physics - Phenomenologytext
