我们研究了一类SO（10）统一模型的第三代Yukawa耦合统一，该统一模型与费米实验室E989实验中看到的μ子g−2标准模型的4.2 σ偏差一致。最近对超重力大统一模型的分析表明，这种效应可能来自超对称环的修正。利用神经网络进一步分析了参数空间中与费米实验室结果一致的汤川耦合统一可能出现的区域。在分析中，我们考虑了三次和四次相互作用对Yukawas的贡献。我们在高亮度和高能的大型强子对撞机上对模型进行了测试，并估计了发现模型预测的粒子所需的综合光度。
We investigate the Yukawa coupling unification for the third generation in a class of SO (10) unified models which are consistent with the 4.2 σ deviation from the standard model of the muon g− 2 seen by the Fermilab experiment E989. A recent analysis in supergravity grand unified models shows that such an effect can arise from supersymmetric loops correction. Using a neural network, we further analyze regions of the parameter space where Yukawa coupling unification consistent with the Fermilab result can appear. In the analysis we take into account the contributions to Yukawas from the cubic and the quartic interactions. We test the model at the high luminosity and high energy LHC and estimate the integrated luminosities needed to discover sparticles predicted by the model.
