Since SO(10) GUTs unify all fermions of the Standard Model plus a right-chiral neutrino in a representation 16 per family, they have the potential to be maximally predictive regarding the ratios between the masses (or Yukawa couplings) of different fermion types, i.e. the up-type quarks, down-type quarks, charged leptons and neutrinos. We analyze the predictivity of classes of SO(10) (SUSY) GUT models for the fermion mass ratios, where the Yukawa couplings for each family are dominated by a single effective GUT operator of the schematic form 16 2 · 45 n · 210 m · H , for H ∈ { 10 , 120 , 126 ¯ $$ \overline{\mathbf{126}} $$ }. This extends previous works to general vacuum expectation value directions for GUT-scale VEVs and to larger Higgs representations. In addition, we show that the location of the MSSM Higgses in the space of all doublets is a crucial aspect to consider. We discuss highly predictive cases and illustrate the predictive power in toy models consisting of masses for the 3rd and 2nd fermion family.

不可重整化 SO(10) GUT 模型中的 Yukawa 比率预测

由于 SO(10) GUT 将标准模型的所有费米子和右手性中微子统一为每个家族 16 个,因此它们有可能最大程度地预测不同费米子类型的质量(或汤川耦合)之间的比率,即上型夸克、下型夸克、带电轻子和中微子。我们分析了费米子质量比的 SO(10) (SUSY) GUT 模型类别的预测性,其中每个系列的 Yukawa 耦合由示意图形式 16 2 · 45 n · 210 m · 的单个有效 GUT 算子主导H ,对于 H ∈ { 10 , 120 , 126 ¯ $$ \overline{\mathbf{126}} $$ }。这将以前的工作扩展到 GUT 规模 VEV 的一般真空期望值方向和更大的 Higgs 表示。此外,我们表明 MSSM Higgses 在所有双峰空间中的位置是一个需要考虑的关键方面。我们讨论了高度预测的案例,并说明了由第三和第二费米子族的质量组成的玩具模型的预测能力。
