Data Selection in the SOX experiment — •Birgit Neumair for the Borexino collaboration — James-Franck-Straße 1, 85748 Garching bei München

In the last years, several neutrino oscillation experiments reported results not compatible within the 3-neutrino model, which hint at 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 a (100-150) kCi ¹⁴⁴Ce - ν_e - source underneath the liquid scintillator detector Borexino. Oscillations will be observed via a reduction of the detected interaction rate of the ν_e and an oscillatory pattern as a function of the neutrino energy and travelled distance. In the talk the data selection will be presented.
