论文摘要
我们研究了n = 1个超级重力模型的宇宙学演化，该模型对与标量场相连的较高导数超级重力模型的双重演变，因此在爱因斯坦框架中，模型是无鬼的。我们发现，该模型承认缓慢的滚动通货膨胀解决方案基本上显示了两体膨胀。与Starobinsky通货膨胀模型相比，该模型计算的宇宙学参数位于可接受的范围内，lnn/n，n是电子折叠的数量。
We study the cosmological evolution of a N = 1 supergravity model, dual to a higher derivative supergravity model coupled to scalar fields so that in the Einstein frame the model is ghost free. We find that this model admit slow roll inflationary solutions showing essentially two-field inflation. The cosmological parameters calculated for this model lie in acceptable range with corrections of the order lnN/N, N being the number of e-foldings, compared to the Starobinsky inflation model.
