论文摘要
我们探索了$（10）$轴模型的一些实验测试预测，该预测包括两个10件费米子，以解决轴突域壁问题。通货膨胀后可以安全地破坏轴突对称性，因此与轴突场相关的异性外观扰动却忽略不计。 $（10）$的不间断量规$ z_2 $对称性可确保存在稳定的wimp般的暗物质，这是fermion 10-plets中的electroweak doublet的线性组合，以及$ so（10）$ singlet fermion live singlet fermion ass $ $ \ sim 62.5 \; {\ rm gev} \; （1 \; {\ rm tev}）$当它主要是单元（Doublet）fermion时，它会与轴线暗物质共存。我们还讨论了量规耦合统一，质子衰减，与重力和静脉生成非最小偶联的膨胀。 With the identification of the SM singlet Higgs field in the $126$ representation of $SO(10)$ as inflaton, the magnetic monopoles are inflated away, and we find $0.963 \lesssim n_s \lesssim 0.965$ and $0.003 \lesssim r \lesssim 0.036$, where $n_s$ and $r$ denote the scalar spectral index and张量比比率分别。这些预测可以在以后的实验中进行测试，例如CMB-S4。
We explore some experimentally testable predictions of an $SO(10)$ axion model which includes two 10-plets of fermions in order to resolve the axion domain wall problem. The axion symmetry can be safely broken after inflation, so that the isocurvature perturbations associated with the axion field are negligibly small. An unbroken gauge $Z_2$ symmetry in $SO(10)$ ensures the presence of a stable WIMP-like dark matter, a linear combination of the electroweak doublets in the fermion 10-plets and an $SO(10)$ singlet fermion with mass $\sim 62.5 \; {\rm GeV}\; (1 \; {\rm TeV}) $ when it is mostly the singlet (doublet) fermion, that co-exists with axion dark matter. We also discuss gauge coupling unification, proton decay, inflation with non-minimal coupling to gravity and leptogenesis. With the identification of the SM singlet Higgs field in the $126$ representation of $SO(10)$ as inflaton, the magnetic monopoles are inflated away, and we find $0.963 \lesssim n_s \lesssim 0.965$ and $0.003 \lesssim r \lesssim 0.036$, where $n_s$ and $r$ denote the scalar spectral index and tensor-to-scalar ratio, respectively. These predictions can be tested in future experiments such as CMB-S4.
