- Title
- What causes the short-baseline neutrino anomalies?
- Plain
- LSND and MiniBooNE saw extra electron-like events, and gallium detectors saw too few neutrino captures. These do not fit the three-neutrino picture.
- Precise
- Explain the LSND (1995) and MiniBooNE electron-like excesses and the gallium deficit in a single consistent framework, or show they have separate conventional origins. An answer is the mechanism (sterile oscillation, decaying heavy states, new interactions, or background and cross-section mismodeling) consistent with disappearance limits.
- Settled by
- The Fermilab SBN program (SBND, MicroBooNE, ICARUS) measuring $\nu_e$ appearance and $\nu_\mu$ disappearance with one technology at several baselines.
