论文摘要
在本文中，我们使用字符串场理论分析了通货膨胀宇宙学。这是通过使用字符串场理论的零级贡献来完成的，这是一种非本地速度作用。我们将基于字符串字段理论为此模型使用非本地Friedmann方程，并计算此模型的慢速参数。然后，我们将明确获得该模型的标量和张力功率谱，其相关索引以及张量比比率。最后，我们使用从Planck 2013到2018的宇宙学数据来限制此模型中的自由参数，并发现字符串场理论与它们兼容。
In this paper, we analyze the inflationary cosmology using string field theory. This is done by using the zero level contribution from string field theory, which is a non-local tachyonic action. We will use the non-local Friedmann equations for this model based on string field theory, and calculate the slow-roll parameters for this model. We will then explicitly obtain the scalar and tensorial power spectrum, their related indices, and the tensor-to-scalar ratio for this model. Finally, we use cosmological data from Planck 2013 to 2018 to constrain the free parameters in this model and find that string field theory is compatible with them.
