论文摘要

我们认为,在堆叠在$ n $平行的域壁上的五维Minkowski空间中,浸入五维的Minkowski空间中,考虑了一个充气的3D域墙。它们是5D超级理论的骨骼部门的静态BPS解决方案。但是,由于散装粒子碰撞和{\ IT共振隧道效应}之间的吸引力,人们可以彼此相互移动。加速域壁是一个三大武器,被认为是我们的早期宇宙。我们分析了该通货膨胀阶段,该通货膨胀阶段受Brane引起的充气电位的控制。我们计算慢速参数,并表明光谱指数和张量表比率在最近的观察数据范围内。

We consider a brane cosmology scenario by taking an inflating 3D domain wall immersed in a five-dimensional Minkowski space in the presence of a stack of $N$ parallel domain walls. They are static BPS solutions of the bosonic sector of a 5D supergravity theory. However, one can move towards each other due to an attractive force in between driven by bulk particle collisions and {\it resonant tunneling effect}. The accelerating domain wall is a 3-brane that is assumed to be our inflating early Universe. We analyze this inflationary phase governed by the inflaton potential induced on the brane. We compute the slow-roll parameters and show that the spectral index and the tensor-to-scalar ratio are within the recent observational data.
