摘要: We find that magnetic neutrino-electron scattering is unaffected by oscillations for vacuum mixing of Dirac neutrinos with only diagonal moments and Majorana two flavors. For Mikheyev-Smirnov-Wolfenstein mixing, these cases are again obtained, though the effective can depend on neutrino energy. Thus, e.g., measured νe from a reactor Sun could be different. With minimal assumptions, we new limit μν using 825-d Super-Kamiokande solar data: |μν|≤1.5×10^-10 μB at 90% CL, comparable to existing limit.
