我们考虑了一个在10{sup 16} GeV左右统一尺度M{sub G}的现象学上可行的SO（10）大统一模型，它再现了低能量下的最小超对称标准模型，并允许在普朗克尺度M{sub P}或弦尺度M{sub st}上进行微扰计算。这两个要求都强烈地限制了模型中希格斯表示的选择。我们提出了一个简单的SO（10）模型，包含一组希格斯表示{l_brace}2x10+16+16+45{r_brace}，并证明了其现象学可行性。该模型确实能够再现与带电费米子质量和混合有关的低能实验数据。中微子振荡数据可以一致地纳入模型，导致右手中微子质量尺度M{sub R}{近似等于}M{sub G}{sup 2}/M{sub P}。此外，还存在一个参数区，使质子寿命与实验结果一致。
We consider a phenomenologically viable SO(10) grand unification model of the unification scale M{sub G} around 10{sup 16} GeV which reproduces the minimal supersymmetric standard model at low energy and allows perturbative calculations up to the Planck scale M{sub P} or the string scale M{sub st}. Both requirements strongly restrict a choice of Higgs representations in a model. We propose a simple SO(10) model with a set of Higgs representations {l_brace}2x10+16+16+45{r_brace} and show its phenomenological viability. This model can indeed reproduce the low-energy experimental data relating the charged fermion masses and mixings. Neutrino oscillation data can be consistently incorporated in the model, leading to the right-handed neutrino mass scale M{sub R}{approx_equal}M{sub G}{sup 2}/M{sub P}. Furthermore, there exists a parameter region which results the proton lifetime consistent with the experimental results.
