Why is TeV-scale a geometric mean of neutrino mass and GUT-scale?

Among three typical energy scales, a neutrino mass scale ($m_{\nu }\sim$ 0.1 eV), a GUT scale ($M_{GUT}\sim {10}^{16}$ GeV), and a TeV-scale ($M_{NP}\sim 1$ TeV), there is a fascinating relation of $M_{NP}\simeq \sqrt{m_\nu\cdot M_{GUT}}$\mathrm{.}TheTeV-scale,$M_{NP}$, 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 $m_{\nu }$ through a tiny vacuum expectation value of neutrinophilic Higgs without additional scales other than $M_{NP}$ and $M_{GUT}$. A gauge coupling unification, which is an excellent feature in the supersymmetric standard model, is preserved automatically in this setup.
