论文摘要
宇宙微波背景的特征提供了间接证据，表明早期宇宙中热辐射主导的时期是通货膨胀膨胀的时期。在这里，我们展示了随机重力波背景的测量如何揭示宇宙历史和通货膨胀期间的身体状况，随后的预热和重新加热以及热爆炸时代的开始。标准模型的特殊动力和预测性最小扩展为众所周知，它为粒子物理学提供了完整的模型 - 直至普朗克量表和宇宙学 - 回到通货膨胀。
The characteristics of the cosmic microwave background provide circumstantial evidence that the hot radiation-dominated epoch in the early universe was preceded by a period of inflationary expansion. Here, we show how a measurement of the stochastic gravitational wave background can reveal the cosmic history and the physical conditions during inflation, subsequent pre- and re-heating, and the beginning of the hot big bang era. This is exemplified with a particularly well-motivated and predictive minimal extension of the Standard Model which is known to provide a complete model for particle physics -- up to the Planck scale, and for cosmology -- back to inflation.
