Abstract: The observation of the coherent elastic neutrino-nucleus scattering process using reactor antineutrinos offers a unique opportunity to probe the Standard Model and explore beyond the Standard Model scenarios. This study reports on the latest results from the CONUS + experiment conducted at the Leibstadt nuclear power plant in Switzerland. The CONUS collaboration reports 395 ± 106 events detected from reactor antineutrinos with an exposure of 327 kg · days , utilizing high-purity germanium detectors operated at sub-keV thresholds. A χ 2 -based statistical analysis was performed on these results, incorporating systematic uncertainties. This analysis was used to extract the weak mixing angle, establish a limit on the neutrino magnetic moment, and impose constraints on neutrino nonstandard interactions using reactor antineutrinos. The results confirm the potential of coherent elastic neutrino-nucleus scattering experiments in the study of fundamental neutrino properties and probing new physics.
