2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/45610We present the results of an analysis of the data of reactor and accelerator neutrino oscillation experiments in the framework of a model with mixing of three massive neutrino fields and a neutrino mass hierarchy. The results of the LSND experiment are commented. Taking into account future long-baseline neutrino oscillation experiments, we have also analyzed the atmospheric neutrino data in the framework of the model.LaTeX file, 6 pages with 2 figures (included).
