Novel constraints on neutrino physics beyond the standard model of elementary particles from the CONUS experiment — •Dario Piani, Nicola Ackermann, Hannes Bonet, Christian Buck, Janina Hakenmüller, Janine Hempfling, Gerd Heusser, Manfred Lindner, Werner Maneschg, Kaixiang Ni, Thomas Rink, Edgar Sánchez García, and Herbert Strecker — MPIK, Heidelberg, Germany

The detection of coherent elastic neutrino-nucleus scattering (CEνNS) opens up new opportunities for neutrino physics within and beyond the standard model of elementary particles. Constantly refining the setup, the experiment CONUS provides valuable data towards the detection of such events from reactor (anti)neutrinos emitted by the powerful 3.9 GW reactor of the nuclear power plant in Brokdorf (Germany). The acquired CONUS data sets enable further investigations on neutrino physics beyond the standard model, such as yet undetected neutrino channels. This talk will explore constraints on beyond the standard model neutrino phenomenology from not yet analyzed data. Bounds on non-standard neutrino-quark interactions of vector type from CEνNS are presented. Furthermore, the parameter space of simplified scalar and vector mediators probed by CEνNS and elastic neutrino-electron scattering is discussed.
