In 1956 Reines & Cowan discovered the neutrino using a liquid scintillator detector. The neutrinos interacted with the scintillator, producing light that propagated across transparent volumes to surrounding photo-sensors. This approach has remained one of the most widespread and successful neutrino detection technologies used since. This article introduces a concept that breaks with the conventional paradigm of transparency by confining and collecting light near its creation point with an opaque scintillator and a dense array of optical fibres. This technique, called LiquidO, can provide high-resolution imaging to enable efficient identification of individual particles event-by-event. A natural affinity for adding dopants at high concentrations is provided by the use of an opaque medium. With these and other capabilities, the potential of our detector concept to unlock opportunities in neutrino physics is presented here, alongside the results of the first experimental validation.

    A new differential decay width including neutral and charged current interference is used to show that future detectors could probe HNL mixing angles over two orders of magnitude below current bounds.

  3. Elastic neutrino-electron scattering perspectives at nuclear reactors

    hep-ph 2026-02 conditional novelty 5.0 of 10

    Projections show CLOUD and TAO could improve low-energy weak mixing angle measurements to 8-11% via elastic neutrino-electron scattering, with competitive magnetic moment and NSI limits.
