Using the movable IWCD near detector at Hyper-Kamiokande, the NCQE-to-CCQE event ratio sampled at three off-axis angles can constrain axial and vector neutrino non-standard interactions at the 0.05 to 0.12 level, breaking degeneracies that a fixed spectrum cannot.

abstract
Extreme astrophysical environments provide unique laboratories for testing fundamental neutrino interactions. We present the first oscillation-independent astrophysical probe of nonstandard neutrino interactions (NSI), using coincident neutral-current signals across diverse detectors to break degeneracies that have long limited sensitivity reach. Using self-consistent NSI supernova simulations and flavor-independent neutral-current scattering we show that anti-correlated signatures between JUNO liquid scintillator and dark matter detectors such as DARWIN/XLZD, ARGO, or RES-NOVA enable clear discrimination between NSI and flavor-conversion effects. For a Galactic supernova at Betelgeuse distance our approach enables an independent probe of neutrino-quark NSI couplings in parameter space that can reach and extend beyond current terrestrial limits. This multidetector approach enables breaking degeneracies in terrestrial searches and is broadly applicable to a wide range of upcoming experiments, establishing a new principle for testing fundamental interactions with astrophysical data.

Moving a Detector to Probe New Neutrino Interactions: IWCD at Hyper-Kamiokande
Using the movable IWCD near detector at Hyper-Kamiokande, the NCQE-to-CCQE event ratio sampled at three off-axis angles can constrain axial and vector neutrino non-standard interactions at the 0.05 to 0.12 level, breaking degeneracies that a fixed spectrum cannot.
