The 3rd Workshop on "Neutrino Oscillations and their Origin" 

The 3rd International Workshop on Neutrino Oscillations and their Origin (NOON2001) will be held at Kashiwa-campus of the Institute for Cosmic Ray Research, University of Tokyo, Japan, December 5th through December 8th of 2001.

Initiated by the discovery of neutrino oscillations in atmospheric neutrinos in Super-Kamiokande, the series of the workshop entitled "Neutrino Oscillations and their Origin" has been held since 2000 in Japan.
In this year, another evidence for neutrino oscillations has been found in solar neutrinos, combining the results of Super-Kamiokande and SNO results. These discoveries carry the investigation of neutrino oscillations a step further and give us hints to search for the origin of neutrino masses. In the workshop, we will discuss latest experimental results, phenomenological theoretical analysis, and theoretical implications which predicts neutrino oscillations. Topics in the workshop are atmospheric neutrinos (experimental results and flux predictions), solar neutrinos (experimental results, solar models and nuclear cross sections), phenomenology of the neutrino oscillations, theoretical origin of neutrino oscillations (GUTs etc.), and lepton flavor violation processes. As a 3rd workshop, we have a stress on the following subjects: 1) precisions of the determination of the mixing and mass matrices in near future; 2) theoretical implications of the different solar neutrino solutions, MSW-LMA, LOW or quasi-Vacuum; 3) constraints on the sterile neutrinos from the experimental data; 4) constraint on neutrino masses from supernovae, 5) relation between neutrino oscillations and double beta decay, and so on.

In this workshop, we bring experimentalists and theorists together and discuss about those subjects.
