Neutrino Oscillations
Super-Kamiokande (1998) shows that neutrinos change type in flight, so they have mass: a first crack in the Standard Model.
Open in the interactive tree →Atmospheric neutrinos in Japan and solar neutrinos at SNO in Canada (2001) earned Kajita and McDonald the 2015 Nobel Prize. The absolute neutrino masses are still being measured.
