We consider the possibility of the lightest sterile neutrino being the dark matter candidate, with a dipole interaction with heavier sterile neutrinos. We find that a light sterile neutrino in the MeV range, with a dimension-five nonrenormalizable dipole interaction suppressed by ?5 greater than or similar to 1015 GeV, can be a good dark matter candidate, while heavier sterile neutrinos in the GeV range can explain active neutrino oscillations.
We consider the possibility of the lightest sterile neutrino dark matter which has dipole interaction with heavier sterile neutrinos. The lifetime can be long enough to be a dark matter candidate without violating other constraints and the correct amount of relic abundance can be produced in the early Universe. We find that a sterile neutrino with the mass of around MeV and the dimension-five nonrenormalizable dipole interaction suppressed by ?5 greater than or similar to 1015 GeV can be a good candidate of dark matter, while heavier sterile neutrinos with masses of the order of GeV can explain the active neutrino oscillations.
