全息宇宙学中的再加热与粒子物理学中的$Λ$ - MSSM结构
Reheating in holographic cosmology and connecting to $Λ$-MSSM constructions for particle physics
摘要：
在本文中，我们模型的过渡，从非几何全息宇宙学制度，通常的辐射主导（RD）宇宙学，被称为再加热的情况下（微扰）通货膨胀。我们发现，我们可以很容易地过渡到任何MSSM结构的相交D 6-膜，通过$α'$的三维场论以及宇宙学的校正，随后通过S-NS 5-膜的宇宙学再加热。而且，我们可以自然地得到观测数量级的（真实的）宇宙学常数$Λ$。由此产生的超对称破缺刚好在目前观测到的能量之外。该模型与大（TeV尺度）的额外维度是一致的，但它更喜欢较小的维度，并且弦尺度一般较低。
英文摘要：
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.
