Neutrino Oscillations Neutrino oscillations means that the neutrinos, that can be produced and detected in three species - flavors, oscillate between the flavors as they propagate from source to detector.
Neutrino oscillations can occur if neutrinos have masses that are nonzero and different.
In the Standard Model of elementary particles this cannot take place. Evidence for neutrino oscillations is therefore an indication of New Physics beyond the Standard Model. In the early summer of '98 the Super-Kamiokande collaboration reported evidence for neutrino oscillations related to the atmospheric neutrino problem. This has rekindled an interest to interpret all deviations from expected results in neutrino physics in terms of neutrino oscillations. We are working on several problems in the realm of neutrino oscillations.
