When was the first evidence for neutrino oscillation reported?
PhysicsParticle physics
Quick Answer
In the 1990s, experiments such as Super-Kamiokande reported strong evidence that neutrinos change flavor.
The Full Story
Strong evidence for neutrino oscillation emerged in the 1990s, especially from the Super-Kamiokande experiment in Japan, which began reporting results in 1998. Neutrino oscillation means neutrinos can change from one type to another as they travel. This showed that neutrinos have mass, contradicting the original Standard Model assumption that they did not. The discovery reshaped particle physics and earned the 2015 Nobel Prize in Physics for Takaaki Kajita and Arthur B. McDonald.
