Super-Kamiokande: evidence that neutrinos change flavour

Contribution grade

Physics · Scoped scientific or research-capability contribution

Reference score170,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

Observed an atmospheric-neutrino pattern consistent with flavour oscillation, providing evidence for nonzero neutrino mass differences.

Scientific scope

Observed an atmospheric-neutrino pattern consistent with flavour oscillation, providing evidence for nonzero neutrino mass differences. Scope limitation: The inference concerns oscillations, not an absolute neutrino-mass measurement. The deposited collaboration byline is retained.

Evidence

Assessment uses the catalogue-linked source evidence for the stated contribution. The inference concerns oscillations, not an absolute neutrino-mass measurement. The deposited collaboration byline is retained.
