Abstract
Among three typical energy scales, a neutrino mass scale (mν∼0.1 eV), a GUT scale (MGUT∼1016 GeV), and a TeV scale (MNP∼1 TeV), there is a fascinating relation, i.e. . The TeV scale, MNP, is a new physics scale beyond the standard model which is regarded as supersymmetry in this letter. We suggest a simple supersymmetric neutrinophilic Higgs doublet model, which realizes the above relation dynamically as well as the suitable mν through a tiny vacuum expectation value of the neutrinophilic Higgs doublet without additional scales other than MNP and MGUT. A gauge coupling unification, which is an excellent feature in the supersymmetric standard model, is preserved automatically in this setup.
