膜上的速子对数介质膨胀

Tachyon Logamediate inflation on the brane

Vahid Kamali, Elahe Navaee Nik

摘要:

根据宇宙尺度因子的Barrow解,在RSII膜世界框架下研究了快子暴胀模型的主要性质。在此框架内的基本慢滚参数的计算分析。我们将这一通胀情景与最新的观测数据进行了比较。预测的谱指数和张量-标量涨落比与{ \it Planck 2015}的结果非常吻合。目前的预测与那些可行的通货膨胀模型是一致的。

英文摘要:

According to a Barrow's solution for the scale factor of the universe, the main properties of the tachyon inflation model in the framework of RSII braneworld are studied. Within this framework the basic slow-roll parameters are calculated analytically. We compare this inflationary scenario against the latest observational data. The predicted spectral index and the tensor-to-scalar fluctuation ratio are in excellent agreement with those of {\it Planck 2015}. The current predictions are consistent with those of viable inflationary models.
