论文摘要
我们考虑了一个受紫外线保护的自然通胀情景，涉及加利福尼亚与标准模型量规场之外的一些类似Chern-Simons的相互作用。宇宙的加速膨胀得到了重力增强的摩擦敏感的对通货膨胀范围和与量规波动爆炸性产生相关的量表的组合。这两种速度行动机制的协同作用允许：$ i）$自然通货膨胀潜力，仅涉及亚planckian耦合常数，$ ii）$以原始黑孔的形式产生暗物质成分，以及$ iii）$ $ iii）$在小规模的chiral pressitation Wave的潜在可观察到的背景。
We consider an UV-protected Natural Inflation scenario involving Chern-Simons-like interactions between the inflaton and some beyond the Standard Model gauge fields. The accelerated expansion of the Universe is supported by a combination of a gravitationally-enhanced friction sensitive to the scale of inflation and quantum friction effects associated with the explosive production of gauge fluctuations. The synergy of these two velocity-restraining mechanisms allows for: $i)$ Natural Inflation potentials involving only sub-Planckian coupling constants, $ii)$ the generation of a dark matter component in the form of primordial black holes, and $iii)$ a potentially observable background of chiral gravitational waves at small scales.
