论文摘要
我们从重力波观测中与宇宙弦张力的边界重新审视D期，并考虑符合哈勃张力的预分解分辨率的$λ$ CDM模型相比，请考虑光谱指数的可能偏差。在这些限制下，D期通货膨胀需要非常小的耦合常数。我们表明，在Brane的D期 - 膨胀的情况下，可以实现天然耦合常数（$ g =λ= 0.1 $）。
We revisit D-term inflation with the bounds of the cosmic string tension from gravitational wave observations and consider the possible deviation of the spectral index compared with the $Λ$CDM model in light of prerecombination resolutions of the Hubble tension. D-term inflation requires very small coupling constants under these constraints. We show that natural coupling constants ($g=λ=0.1$) can be achieved in the case of D-term inflation on the brane.
