Dr Walter Potzel (Physik-Department E15, Technische Universität München, D-85748 Garching, Germany)In direct dark-matter search experiments, neutrinos coherently scattering off nuclei can produce similar events as Weakly Interacting Massive Particles (WIMPs). Calculations show, that in such experiments, for solar neutrinos a count rate of a few events per ton of target mass and year of exposure are expected. This count rate strongly depends on the nuclear recoil-energy thresholds achieved...Go to contribution page
