The asymmetry of solar-neutrino fluxes

With effective heliolatitude Leff(n) for each solar-neutrino run n we separate all available Homestake experimental data for more than two solar cycles (1970–1994) on three zones SOUTH, EQUATORIAL, and NORTH in dependence on the heliolatitude (where detected neutrinos cross the Sun’s surface). For each latitudinal zone, we determine the average solar electron neutrino flux and correlations with effective solar-activity parameters for asymmetrical latitudinal belts. The obtained results indicate that neutrino should have nonzero mass and nonzero magnetic moment.
