Electron antineutrino disappearance at KamLAND and JUNO as decisive tests of the short baseline [bar over ν][subscript μ] → [bar over v][subscript e] appearance anomaly
The IsoDAR antineutrino source, which produces a flux from [superscript 8]Li isotope decay at rest, when paired with the proposed Jiangmen Underground Neutrino Observatory detector, has unprecedented sensitivity to [bar over ν][subscript e] disappearance for oscillations at high Δm[superscript 2].

| Summary: | The IsoDAR antineutrino source, which produces a flux from [superscript 8]Li isotope decay at rest, when paired with the proposed Jiangmen Underground Neutrino Observatory detector, has unprecedented sensitivity to [bar over ν][subscript e] disappearance for oscillations at high Δm[superscript 2]. Assuming charge conjugation, parity transformation, and time reversal (CPT) invariance, the sensitive region for [bar over ν][subscript e] disappearance can be used to restrict the allowed parameter space of a [bar over ν][subscript μ] → [bar over ν][subscript e] appearance signal. The 5σ sensitivity of this experiment covers the entire [bar over ν][subscript μ] → [bar over ν][subscript e] allowed parameter space from a combined fit to short-baseline experiments. This represents a decisive test of the LSND neutrino experiment and MiniBooNE antineutrino appearance signals within all models that are CPT invariant. Running IsoDAR at KamLAND restricts a large part of the appearance signal region in a similar way. |
