Vacuum oscillation probability
The signature expression of neutrino oscillation. The observation that this probability is non-zero forced the Standard Model to accommodate non-degenerate neutrino masses.

Formulas
Three equations at the heart
of neutrino physics.
The expression that made oscillation measurable. The coherent cross-section that opened low-energy neutrino detection. The engineering-integration framework that connects them to applied research.
CEvNS coherent cross-section
Coherent elastic neutrino-nucleus scattering scales quadratically with neutron number — the largest neutrino cross-section below 50 MeV. Predicted by Freedman 1974, observed by COHERENT 2017.
See CEvNS concept →Schubart Master Equation
The engineering-integration framework for neutrinovoltaic conversion — packaging CEvNS, cosmic-ray muon flux, ambient electromagnetic, and thermal contributions into a single expression for device output power.
