Flavor changing models with strictly massless neutrinos
M. M. Guzzo, H. Nunokawa, O. L. G. Peres +2
Theoretical models which present flavor changing neutrino interactions and simultaneously prevent this particle from acquiring any mass exist. We discuss some of them and their pre…
Model Independent Analysis of the Solar Neutrino Data
Hisakazu Minakata, Hiroshi Nunokawa
We perform an updated model-independent analysis using all the latest solar neutrino data, including the one coming from remarkably high statistics SuperKamiokande experiment. We c…
Update on Atmospheric Neutrinos
M. C. Gonzalez-Garcia
I summarize here the results of a global fit to the full data set corresponding to 535 days of data of the Super-Kamiokande experiment as well as to all other experiments in order…
Supernova Bounds on Neutrino Properties: a mini-review
Hiroshi Nunokawa
This talk summarizes our recent work which studied the impact of resonant neutrino conversion induced by some non-standard neutrino properties beyond mass and mixing, such as neutr…
The MSW conversion of solar neutrinos and random matter density perturbations
H. Nunokawa, A. Rossi, V. B. Semikoz +1
We present a generalization of the resonant neutrino conversion in matter, including a random component in the matter density profile. The study is focused on the effect of such ma…
