论文摘要
受到CDF协作最近确定$ W $ -BOSON质量的启发，我们重新访问了$ SO（10）$ AXION模型，其中标量$ su（2）_l $ su（2）_l $ Triplet Field具有零超充血，可以通过与标准模型Higgs Doublet的混合来获取非零VEV。 Triplet VEV为$ W $质量提供了相当大的贡献，这有助于大大降低标准模型预测与$ M_W $的较高CDF值之间的$7σ$差异。我们表明，相对较轻的三重质量质量（$ \ sim（1-50）$ tev）与量规耦合统一和可观察的质子衰变兼容。一个不间断的$ Z_2 $量规对称性，再加上两个Fermionic $ 10 $ 10 $ 10 $ - 解决轴突域壁问题，这意味着轴和一个稳定的中间质量（$ \ sim 10^9-10^{10} {10} $ GEV）fermion fermion fermion fermion均为可见的深色黑物问题。我们还显示了该模型预测的拓扑稳定宇宙字符串的重力波谱。
Inspired by the recent determination of the $W$-boson mass by the CDF collaboration, we revisit an $SO(10)$ axion model in which a scalar $SU(2)_L$ triplet field with zero hypercharge is known to acquire a non-zero VEV through its mixing with the Standard Model Higgs doublet. The triplet VEV provides a sizable contribution to the $W$ mass, which helps in significantly lowering the $7σ$ discrepancy between the Standard Model prediction and the higher CDF value for $m_W$. We show that the relatively light triplet mass ($\sim (1-50)$ TeV) is compatible with gauge coupling unification and observable proton decay. An unbroken $Z_2$ gauge symmetry, coupled with the presence of two fermionic $10$-plets required to resolve the axion domain wall problem, means that both axions and a stable intermediate mass ($\sim 10^9-10^{10}$ GeV) fermion are plausible dark matter candidates. We also display the gravitational wave spectrum from the intermediate scale topologically stable cosmic strings predicted by the model.
