Grating Física, Astronomía y Matemáticas Neutrino oscillations Atmospheric neutrinos In this work we try to understand the phenomena of neutrino oscillations, and use this to obtain a more precisedescription of the atmospheric neutrino data. The two neutrino oscillation mechanism solves the problemof the up-down muon neutrino asymmetry successfully. Our main motivation is to describe the excess of eventsof electron-neutrino type found in the SuperKamiokande results at low energies when compared with the predictionsof the two-generation neutrino oscillation. To do this we generalize the oscillation model from two tothree neutrino flavors, opening the possibility of oscillation between electron neutrino type and the others. Thenwe obtain a semi-analytic solution of the three flavors problem using the neutrino phenomenological limits onoscillation parameters, squared masses differences and mixing angles. For this we must take into account mattereffects on the electronic neutrino when it cross the Earth and has its oscillation pattern changed. 2007 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46437427 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.2B Vol.37 |
