Description
After the first observation of coherent elastic neutrino-nucleus scattering (CE$\nu$NS), the question arises how to further exploit this signal for a wide variety of future investigations. In this context, nuclear reactors with their intense emission of low-energy antineutrinos in combination with high-purity germanium detectors have already shown their potential for CE$\nu$NS studies and represent a scalable technology for future precision experiments. Measurements such as those performed by the CONUS collaboration are of interest since deviations from the Standard Model CE$\nu$NS prediction could indicate the existence of new neutrino interactions. In particular, a light vector boson may imply corrections to the Weinberg angle, so increasing the precision of this observable will help to probe additional U(1) extensions of the Standard Model. In this talk, we discuss the potential of future germanium-based reactor experiments for precision measurements. Using a data-based reactor antineutrino prediction, we present the experimental sensitivity to the weak mixing angle and the parameters of generic light vector models. In addition, the effects of characteristic experimental parameters such as detector mass and energy threshold are presented and it is shown where improvements in detector design could have the strongest impact on physics investigations. Finally, we flesh out our results by showing the potential of the recently announced follow-up experiment CONUS+.
