论文摘要
近年来，已经提出了许多改良的重力模型作为黑暗能量的替代方法。重力理论还需要修改“相对论的一般理论”。在本文中，我们考虑了五种不同的重力理论，并将通货膨胀参数与两个普朗克协作团队发布的最新数据集进行了比较。我们的分析表明，标量调整重力理论是最好的选择。
In the recent years, a host of modified gravity models have been proposed as alternatives to the dark energy. A quantum theory of gravity also requires to modify `General Theory of Relativity'. In the present article, we consider five different modified theories of gravity, and compare inflationary parameters with recent data sets released by two Planck collaboration teams. Our analysis reveals that the scalar-tensor theory of gravity is the best alternative.
