研究暗维度暴胀中的跨普朗克审查猜想，通过高维暴胀连接粒子物理和宇宙学的大层次结构，此提议在特定维度下与原初密度扰动功率谱一致，研究表明该猜想极大限制了模型参数空间。
AI 中文摘要
有人提出，通过高维暴胀连接粒子物理学和宇宙学中的两个大层次结构，即实际引力的微弱与可观测宇宙的巨大，额外维度可以获得大尺寸，这是基于一个基本尺度。该提议仅在一两个微米大小的额外维度下与观测到的原初密度扰动的近似尺度不变功率谱一致。虽然最近研究了连接高维暴胀时期与标准宇宙学开始的宇宙学历史，但我们在此背景下研究跨普朗克审查猜想，并表明它极大地限制了模型的参数空间。
英文摘要
It was proposed that extra dimensions can acquire large size by higher dimensional inflation connecting two large hierarchies in particle physics and cosmology, namely the weakness of the actual gravitational force to the largeness of the observable Universe, in terms of one fundamental scale. This proposal is consistent with the observed approximate scale invariant power spectrum of primordial density perturbations only for one or two extra dimensions of around the micron size. While a cosmological history connecting the period of higher dimensional inflation to the beginning of the standard cosmology has recently been studied, we investigate here the TransPlanckian Censorship Conjecture in that context and show that it drastically constrains the parameter space of the model.
