Coherent elastic neutrino nucleus scattering as a window to new physics — •Thomas Rink — Max-Planck-Institut für Kernphysik, Heidelberg, Deutschland

With the next generation of low-energy Germanium detectors Coherent Elastic Neutrino Nucleus Scattering is close to first confirmation. Besides establishing a new neutrino reaction channel which is predicted by the standard model for over forty years now, CENNS provides also many opportunities to test recent theoretical models including eV-mass sterile neutrinos as well as non-standard neutrino interactions. Further, another possibility of measuring the Weinberg angle would be established, complementing the rare data situation at lowest energies. This talk shows that the combination of highest possible neutrino fluxes, a sophisticated shielding design and lowest detection energies proves well to reach this aim. By referring to a feasibility study adapted to this requirements, prospects of measuring the signal itself are presented and an outlook of constraining the mentioned BSM models is given. The critical influence of quenching, the conversion of nuclear recoils to ionization signals within the crystal, in such attempts shall be emphasized.
