Description
The detection of coherent elastic neutrino-nucleus scattering (CEνNS) opens up new opportunities for neutrino physics within and beyond the standard model (BSM) of elementary particles. The first detection of CEνNS at nuclear reactors by the CONUS+ experiment allows very valuable tests of BSM scenarios in a low momentum transfer regime. Among them, Non Standard Interactions (NSIs), light mediators (scalar and vector couplings) and electromagnetic properties were tested, setting very competitive limits in both the nuclear scattering interaction channel as well as the electron scattering channel. In particular, for vector NSIs, a sensitivity to new physics of up to 145 GeV was achieved. Whereas, for the light mediators, couplings down to $4 \cdot 10^{−7}$ were probed. Further, the Weinberg angle was constrained and found in good agreement with the Standard Model.
