在三种典型的能量尺度中，中微子质量尺度（$m_\nu\sim $0.1 eV），一种大统一理论标度（$M_{GUT}\sim 10^{16}$ GeV），以及TeV尺度（$M_{NP}\sim $1 TeV），有一个有趣的关系$M_{NP}\simeq \sqrt{m_\nu\cdot M_{GUT}}$. TeV尺度，$M_{NP}$，超对称性是标准模型之外的一种新的物理尺度，本文称之为超对称性。我们研究了具有亲中微子Higgs的超对称SU（5）大统一理论的唯象，它通过亲中微子Higgs的微小真空期望值，动态地实现了上述关系以及Dirac质量的合适大小$m\nu$。该模型的一个显著特点是在保持质子稳定性的前提下实现了精确的规范耦合统一。我们还评估了夸克/轻子部门的味道变化过程。
Among three typical energy scales, a neutrino mass scale ($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 $M_{NP}\simeq \sqrt{m_\nu\cdot M_{GUT}}$.The TeV-scale, $M_{NP}$, 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, $m_\nu$, 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.
