Title: Scanning the Earth with solar neutrinos and DUNE
Speaker: Ara Ioannisian, Yerevan Physics Institute, Armenia
Abstract: We explore oscillations of the solar 8B neutrinos in the Earth in detail. The relative excess of night νe events (the Day-Night asymmetry) is computed as function of the neutrino energy and the nadir angle of its trajectory. The finite energy resolution of the detector causes an important attenuation effect, while the layer-like structure of the Earth density leads to an interesting parametric oscillation effect. About 75 solar neutrino (Eν>11 MeV) events are expected per day in 40 kt DUNE detector. The average D-N asymmetry is expected to be about 4\% and can be measured with 15% accuracy after 5 years of data taking.
