论文摘要
意外的u（1）peccei-quinn（PQ）对称性会自动在SO（10）统一理论的类别中出现，并在衡量SU（3）$ _ {f} $味道组后。 PQ对称性受$ \ Mathbb {z} _4 \ times \ times \ Mathbb {z} _3 $中心的$ \ text {so（10）} \ times \ times \ text {su（3）} _ f $ to to Canonical dimension六的有效操作员。但是，对提出PQ质量问题的斧头电位的高规模贡献仅在$ d = 9 $中出现。在通货膨胀的PQ断裂方案中，轴突质量窗口预计为$ m_a \在[7 \ times 10^{ - 8}，10^{ - 3}] $ eV中，其中下端受Seesaw scale的范围，并由ISO-Curvature Provuctuations界限。以$ M_A \ gtrsim 0.02 $ eV获得的高质量轴是不受PQ质量问题的影响。我们终于在大统一理论中就PQ质量问题提供了一般的看法。
An accidental U(1) Peccei-Quinn (PQ) symmetry automatically arises in a class of SO(10) unified theories upon gauging the SU(3)$_{f}$ flavour group. The PQ symmetry is protected by the $\mathbb{Z}_4 \times \mathbb{Z}_3$ center of $\text{SO(10)} \times \text{SU(3)}_f$ up to effective operators of canonical dimension six. However, high-scale contributions to the axion potential posing a PQ quality problem arise only at $d=9$. In the pre-inflationary PQ breaking scenario the axion mass window is predicted to be $m_a \in [7 \times 10^{-8}, 10^{-3}]$ eV, where the lower end is bounded by the seesaw scale and the upper end by iso-curvature fluctuations. A high-quality axion, that is immune to the PQ quality problem, is obtained for $m_a \gtrsim 0.02$ eV. We finally offer a general perspective on the PQ quality problem in grand unified theories.
