本文研究了膜世界模型中反余双曲势中标量场的暴胀动力学。我们注意到,在高能极限下,考虑慢滚近似的势可以得到一个充分的暴胀。我们确定的初始暴胀子场所需的最小值,以获得足够的通货膨胀,并确定相关的通货膨胀参数。标量扰动谱的谱指数的数值是通过改变暴胀子场的初始值的e折叠数来确定的。所得结果与目前的观测极限符合得很好。
In this paper we study inflationary dynamics with a scalar field in an inverse coshyperbolic potential in the braneworld model. We note that a sufficient inflation may be obtained with the potential considering slow-roll approximation in the high energy limit. We determine the minimum values of the initial inflaton field required to obtain sufficient inflation and also determine the relevant inflationary parameters. The numerical values of spectral index of the scalar perturbation spectrum are determined by varying the number of e-foldings for different initial values of the inflaton field. The result obtained here is in good agreement with the current observational limits.
