Determination of neutrino incoming direction in the CHOOZ experiment and its application to supernova explosion location by scintillator detectors
Abstract
The CHOOZ experiment has measured the antineutrino flux at about 1 km from two nuclear reactors to search for possible ν¯e-->ν¯x oscillations with mass-squared differences as low as 10-3 eV2 for full mixing. We show that the analysis of the ~2700 ν¯e events, collected by our liquid scintillation detector, locates the antineutrino source within a cone of half-aperture ~18° at the 68 % C.L. We discuss the implications of this result for locating a supernova explosion.
