Among three typical energy scales, a neutrino mass scale (m ν∼0.1eV), a GUT scale (MGUT∼10 16GeV), and a TeV-scale (MNP∼1TeV), there is a fascinating relation of MNP≃mνṡM GUT The TeV-scale, MNP, is a new physics scale beyond the standard model which is regarded as "supersymmetry" (SUSY) in this letter. We investigate phenomenology of SUSY SU(5) GUT with neutrinophilic Higgs, which realizes the above relation dynamically as well as the suitable magnitude of Dirac mass, mν, through a tiny vacuum expectation value of neutrinophilic Higgs. As a remarkable feature of this model, accurate gauge coupling unification can be achieved as keeping with a proton stability. We also evaluate flavor changing processes in quark/lepton sectors.
