### Description

The detection of coherent elastic neutrino-nucleus scattering (CE$\nu$NS) opens up new possibilities for neutrino physics within and beyond the standard model. As a leading reactor experiment, CONUS aims at an observation in the coherent energy regime with antineutrinos emitted from the powerful $3.9$ GW$_{\mathrm{th}}$ reactor of the nuclear power plant in Brokdorf (Germany). In particular, the application of ultra-low threshold, high-purity germanium detectors within a compact shield design in close proximity to the nuclear reactor core represents the next milestone towards high-statistics neutrino physics. The data sets collected between April 2018 and June 2019 already allow the investigation of new physics beyond the standard model. This poster illustrates the main components of a realistic signal prediction underlying the statistical analysis performed, and presents constraints on beyond the standard model neutrino phenomenology. Bounds for non-standard neutrino-quark interactions of vector and tensor type from CE$\nu$NS are addressed, and the parameter space of simplified scalar and vector mediators probed by CE$\nu$NS and elastic neutrino-electron scattering is discussed. Finally, limits on an effective neutrino magnetic moment and an effective neutrino millicharge are shown.
