摘要

本文建立了一个现象学暴胀模型，发现光谱指数和张量标量比的预测值与普朗克2018巡天和BICEP/Keck阵列测量结果吻合良好，显著提高了描述早期宇宙暴胀过程的理论精度。膨胀后，我们发现预热可以由速速不稳定性或参数共振引起，这取决于模型参数之一的值。

A model of inflation consistent with Planck 2018 and BICEP/Keck data

We establish a phenomenological inflation model in this paper and find that the predicted values of the spectral index and the tensor-to-scalar ratio are well consistent with the results from the Planck 2018 survey and the BICEP/Keck array measurement, significantly improving the theoretical precision in describing the early universe’s inflationary process. After inflation, we find that preheating can occur from the tachyonic instability or the parametric resonance, which depends on the value of one of model parameters.
