Magnetic dipole moment and keV neutrino dark matter
arXiv:1201.1534 · doi:10.1016/j.physletb.2012.02.080
Abstract
We study magnetic dipole moments of right-handed neutrinos in a keV neutrino dark matter model. This model is a simple extension of the standard model with only right-handed neutrinos and a pair of charged particles added. One of the right-handed neutrinos is the candidate of dark matter with a keV mass. Some bounds on the dark matter magnetic dipole moment and model parameters are obtained from cosmological observations.
