Short-baseline neutrino anomalies and sterile neutrinos
Several experiments saw more or fewer neutrinos than expected over short distances, hinting at a fourth, non-interacting (sterile) neutrino. Newer experiments do not confirm the simplest version, but some excesses remain unexplained.
Why it matters
A sterile neutrino would be a new particle; if none exists, the anomalies expose flaws in neutrino flux or interaction modeling.
