论文摘要
在这项工作中,我们使用改进的均匀近似方法和第三阶相位综合方法来计算Starobinsky通货膨胀模型框架内的张量功率谱和张量比比率R。我们将我们的结果与具有数值集成以及慢速近似为二阶获得的结果进行比较。我们使用不同的近似值获得了R的一致值,并且R在观测值报告的间隔内。
In this work we calculate the tensor power spectrum and the tensor-to-scalar ratio r within the frame of the Starobinsky inflationary model using the improved uniform approximation method and the third-order phase-integral method. We compare our results with those obtained with numerical integration and the slow-roll approximation to second order. We have obtained consistent values of r using the different approximations, and r is inside the interval reported by observations.
