论文摘要
越来越多的证据表明，在遥远星系数量中观察到的宇宙偶极子与宇宙微波背景（CMB）中观察到的宇宙偶极子之间存在差异。在这项研究中，我们研究了宇宙偶极子问题可以通过考虑QCD轴的解决可能性，QCD轴是由Peccei-Quinn对称性的自发断裂产生的假设粒子，并假定构成了我们宇宙中的暗物质。
There is increasing evidence suggesting a discrepancy between the cosmic dipole observed in the number count of distant galaxies and the one derived from the cosmic microwave background (CMB). In this study, we investigate the possibility that the cosmic dipole problem can be addressed by considering the QCD axion, a hypothetical particle that arises from the spontaneous breaking of the Peccei-Quinn symmetry and is postulated to constitute the dark matter in our universe.
