Coverage

The register covers experiments with primary scientific objectives in: three-flavour oscillation parameters, absolute neutrino mass, neutrinoless double beta decay, sterile-neutrino searches, supernova-neutrino detection, and high-energy astrophysical neutrinos. Coherent elastic neutrino-nucleus scattering (CEνNS) experiments are listed where relevant to absolute-mass or beyond-Standard-Model interactions.

We do not maintain a separate listing for accelerator beam facilities (J-PARC, NuMI, BNB, LBNF), reactor complexes, or supernova alert networks (SNEWS); these appear under the relevant experiment entries.
