Implications of the first CONUS + measurement of coherent elastic neutrino-nucleus scattering
Year: 2025
Type: article
Abstract: The CONUS + collaboration has reported their first observation of coherent elastic neutrino-nucleus scattering ( CE ν NS ). The experiment uses reactor electron antineutrinos and germanium detectors with recoil thresholds as low as 160 eV ee . With an exposure of 327 kg × d , the measurement was made with a statistical significance of 3.7 σ . We explore several physics implications of this observation, both within the standard model and in the context of new physics. We focus on a determination of the weak mixing angle, nonstandard and generalized neutrino interactions both with heavy and light mediators, neutrino magnetic moments, and the up-scattering of neutrinos into sterile fermions through the sterile dipole portal and new mediators. Our results highlight the role of reactor-based CE ν NS experiments in probing a vast array of neutrino properties and new physics models.
