Abstract: Among three typical energy scales, a neutrino mass scale (m_[ν] ∼ 0.1 eV), a grand unified theory (GUT) scale (M_[GUT] ∼ 10^[16] GeV), and a TeV scale (M_[NP] ∼ 1 TeV), there is the fascinating relation of M_[NP] ≃ √ m_[ν] ・ M_[GUT] ・ The TeV scale, M_[NP], is a new physics scale beyond the standard model which is regarded as "supersymmetry" in this article. We investigate the phenomenology of the supersymmetry SU(5) GUT with neutrinophilic Higgs, where the above relation is realized dynamically when neutrinos are Dirac particles. As a remarkable feature of this model, accurate gauge coupling unification can be achieved in keeping with a proton stability. We also evaluate flavor changing processes in quark/lepton sectors.
