The magnetic moment of the electron neutrino in mirror models

AbstractThe electromagnetic properties of the electron neutrino are analyzed in theories involving mirror fermions. We find that the magnetic dipole moment of the neutrino can be as large as 10−10 μB, which may explain the observed solar neutrino deficit, as previously suggested. We show that this is not contradictory to other electroweak phenomena. To this end we calculate the weak correction to the anomalous magnetic moment of the electron, from which we get the upper limit for the electron-mirror-electron mixing angle θ≲0.05.

Reconciling dark matter and solar neutrinos

AbstractWe present a simple model for neutrino dark matter in which neutrino masses arise radiatively and the solar neutrino data are explained via the MSW effect. The dark matter scale arises at the one-loop level with the MSW scale arises only in two loops. The model is compatible with all observational facts and allows observable νeντ or νμντ oscillation rates in the laboratory if the limits from primordial big bang nucleosynthesis (BBN) are taken conservatively. In addition, it can be probed by searching for muon number violating processes such as μ→e+γ, and μ→3e. These rates can well lie within the sensitivities of present experiments. Finally, if we ignore BBN limits we can have also a common explanation for the atmospheric neutrino deficit via νμ oscillations to a sterile neutrino νs with maximal mixing and 10−2−10−3 eV2.
