Sterile neutrino search with SOX/Borexino — •Birgit Neumair — for the SOX/Borexino Collaboration. Physik-Department E15, Technische Universität München, Germany
In the last years, several neutrino oscillation experiments reported results not compatible within the 3-neutrino model, which hint to the existence of light sterile neutrinos. To test this hypothesis, the SOX (Short distance neutrino Oscillations in BoreXino) experiment will search for oscillations from active to sterile neutrinos by placing radioactive electron (anti-)neutrino sources underneath the Borexino detector. Oscillations will be observed via a reduction of the detected interaction rate of the electron(anti-)neutrinos and an oscillatory pattern as a function of the neutrino energy and travelled distance. The talk will give an overview of the project and of the expected discovery potential for a 10MCi 51Cr neutrino and a 100kCi 144Ce antineutrino source.
