摘要：

Solar neutrinos with nonzero magnetic moments will contribute to the electron scattering rates in the Super-Kamiokande experiment. The magnetic moment scattering events in Super-K can be accommodated in the standard vacuum oscillation or Mikheyev-Smirnov-Wolfenstein solutions by a change of the parameter space of mass square difference and mixing angle, but the shifted neutrino parameters obtained from Super-K will (for some values of neutrino magnetic moments) become incompatible with the fits from SNO, gallium, and chlorine experiments. We compute the upper bounds on the Dirac and Majorana magnetic moments of solar neutrinos by simultaneously fitting all the observed solar neutrino rates. The bounds of the magnetic moment matrix elements are of the order of 10(-10)mu(B).
