论文摘要
在本文中,我们建模了从非几何全息宇宙学制度的过渡到以(扰动)通货膨胀为主的通常的辐射(RD)宇宙学,被称为重新加热。我们发现,我们可以轻松地通过3维场理论和宇宙学中的$α'U校正以及通过S-NS5-BRANES进行宇宙学重新加热。此外,我们自然可以获得观察到的数量级的(真实的)宇宙常数$λ$。产生的超对称性断裂就在当前观察到的能量之外。该模型与较大(TEV比例)的额外尺寸一致,但是它更喜欢较小的尺寸,并且弦刻度通常很低。
In this paper we model the transition from the non-geometric holographic cosmology regime, to the usual radiation dominated (RD) cosmology, known as reheating in the case of (perturbative) inflation. We find that we can easily transition into any MSSM construction of intersecting D6-branes, via $α'$ corrections in the 3 dimensional field theory as well as in cosmology, followed by cosmological reheating via S-NS5-branes. Moreover, we can naturally obtain the (true) cosmological constant $Λ$ of the observed order of magnitude. The resulting supersymmetry breaking is just outside the currently observed energies. The model is consistent with large (TeV scale) extra dimensions, but it prefers smaller ones, and the string scale is generically low.
