“…We have estimated this contribution -associated with matching the effective theory onto the (unspecified) full theory at high scales -using NDA. The resulting expressions for µ Turning now to the current experimental situation, the best laboratory limit obtained from scattering of low energy reactor neutrinos is "µ e " < 0.7 × 10 −10 µ B [3]. Note that this limit applies to both µ τ e and µ µe , as the flavor of the scattered neutrino is not detected in the experiment.…”

Model independent bounds on magnetic moments of Majorana neutrinos

We analyze the implications of neutrino masses for the magnitude of neutrino magnetic moments. By considering electroweak radiative corrections to the neutrino mass, we derive model-independent naturalness upper bounds on neutrino magnetic moments, µν , generated by physics above the electroweak scale. For Dirac neutrinos, the bound is several orders of magnitude more stringent than present experimental limits. However, for Majorana neutrinos the magnetic moment contribution to the mass is Yukawa suppressed. The bounds we derive for magnetic moments of Majorana neutrinos are weaker than present experimental limits if µν is generated by new physics at ∼ 1 TeV, and surpass current experimental sensitivity only for new physics scales > 10 -100 TeV. The discovery of a neutrino magnetic moment near present limits would thus signify that neutrinos are Majorana particles.

We have obtained a new limit on the electron neutrino effective charge radius from a new evaluation of the weak mixing angle by a combined fit of all electron-(anti)neutrino electron elastic scattering measurements. Weak mixing angle is found to be sin 2 θ W = 0.259±0.025 in the low energy regime below 100 MeV. The electron neutrino charge radius squared is bounded to be in the range −0.13 × 10 −32 cm 2 < r 2 νe < 3.32 × 10 −32 cm 2 at 90% C.L. Both results improve previously published analyses. We also discuss perspectives of future experiments to improve these constraints.
