👤 whose
Whose discovery showed that neutrinos have mass?
Quick Answer
Takaaki Kajita led major results from Super-Kamiokande in 1998 showing neutrino oscillations. Those oscillations imply that neutrinos have mass.
The Full Story
Takaaki Kajita and the Super-Kamiokande collaboration reported strong evidence in 1998 that neutrinos change flavor as they travel. This phenomenon, called neutrino oscillation, can only occur if neutrinos have mass. The result forced a major revision of the Standard Model of particle physics. Kajita shared the 2015 Nobel Prize in Physics with Arthur B. McDonald.
