Muon Neutrino

Second-generation neutrino paired with the muon, first distinguished at Brookhaven in 1962.

Core Principles & Analysis

• Its 1962 discovery at Brookhaven earned Lederman, Schwartz, and Steinberger the 1988 Nobel Prize.
• Atmospheric muon neutrino oscillations, observed by Super-Kamiokande in 1998, proved neutrinos have mass.
• Accelerator beams of muon neutrinos from pion decay feed oscillation experiments like T2K and NOvA.
