  "abstract": "The CONUS+ collaboration has reported their first observation of coherent elastic neutrino-nucleus scattering (CE$\\nu$NS).The experiment uses reactor electron antineutrinos and germanium detectors with recoil thresholds as low as $160~\\mathrm{eV_{ee}}$. With an exposure of $347$ kg $\\times$ d, the measurement was made with a statistical significance of $3.7 \\sigma$. 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, non-standard 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 r\\^ole of reactor-based CE$\\nu$NS experiments in probing a vast array of neutrino properties and new physics models.",
