Problem
In the seesaw mechanism a light neutrino mass arises as mν=mD2/MR, where mD is a Dirac mass and MR is the mass of a heavy right-handed Majorana neutrino, with mD≪MR. A model has a Dirac mass mD=1TeV and is built to give a light neutrino mass mν=0.01eV, of the size suggested by the measured mass splittings. Find the heavy mass scale MR this model needs, in GeV.
