Solar Neutrino Oscillations in the Moon

Many different solar neutrino experiments detect significantly fewer neutrinos than expected. No known modification of the standard solar model can account for all of the data. The most likely explanation is neutrino oscillations, in which many of the electron neutrinos emitted by the core of the Sun convert into other types of neutrinos while traversing the Sun. This explanation will be severely tested within the next few years. We present a pedagogical explanation of the phenomenon of neutrino oscillations, and then use the results to address the question of whether the currently planned neutrino detectors could detect neutrino oscillations in the moon during solar eclipses.
