论文摘要
轴通货膨胀是一种模型,在该模型中,充气电位接近远离原点的高原,而与原点附近的混乱通货膨胀相似。同时,Randall-Sundrum II型模型(RSII)是研究宇宙学现象学的有趣额外模型。在本文中,我们研究了RSII模型中的轴通胀。我们发现这些预测与观察非常吻合。发现基本的五维Planck量表被认为是$ M_5 \ simeq 10^{16} $ GEV,这与从实验性牛顿重力界获得的下限$ m_5 \ gtrsim 10^{9} $ GEV是一致的。这是一个重要的结果,可以用来进一步探索其他维度在其他情况下的含义。
Shaft inflation is a model in which the inflaton potential approaches a plateau far from the origin, while it resembles chaotic inflation near the origin. Meanwhile, the Randall-Sundrum type II model (RSII) is an interesting extra-dimensional model to study cosmological phenomenology. In this paper, we study shaft inflation in the RSII model. We find that the predictions are in excellent agreement with observation. The fundamental five-dimensional Planck scale is found to be $M_5\simeq 10^{16}$ GeV, which is consistent with the lower bound $M_5\gtrsim 10^{9}$ GeV obtained from experimental Newtonian gravitational bound. This is an important result that can be used to explore further the implications of extra dimension in other contexts.
