Research pillar · Informs Φ(E,θ,t), σ(E)
Neutrino Physics
Oscillation, solar and atmospheric measurements, and coherent scattering established neutrinos as real, massive and abundant. This pillar underwrites the flux density Φ(E,θ,t) and the coupling cross-section σ(E).
Deep-dive papers
- Evidence for oscillation of atmospheric neutrinos The measurement that showed atmospheric neutrinos change flavour on their way to the detector — and therefore carry mass. Φ(E,θ,t) Read the deep dive →
- Direct evidence for neutrino flavor transformation from neutral-current interactions The Sudbury Neutrino Observatory measured all three neutrino flavours from the Sun and recovered the total flux stellar models predict. Φ(E,θ,t) Read the deep dive →
- Observation of coherent elastic neutrino–nucleus scattering The first detection of a neutrino scattering off an entire nucleus coherently — a process whose cross-section is enhanced by the square of the neutron number. σ(E) Read the deep dive →
