Neutrino Oscillations and Moments of Electron Spectra
John N. Bahcall, P. I. Krastev, E. Lisi
Abstract
We show that the effects of neutrino oscillations on 8B solar neutrinos are described well by the first two moments (the average and the variance) of the energy distribution of scattered or recoil electrons. For the SuperKamiokande and the Sudbury Neutrino Observatory experiments, the differences between the moments calculated with oscillations and the standard, no-oscillation moments are greater than 3 standard deviations for a significant fraction of the neutrino mass-mixing (Delta m2, sin2 2 theta) parameter space.
