利用解析表达式,我们探索了位势为V0 ± m2 <$2 −a <$p的山顶暴胀模型的参数空间。在正号和p>2的情况下,这将原始的混合暴胀模型转换为山顶模型,使得谱指数与观测值n = 0.95一致。在某些情况下,观察值在理论上是有利的,而在其他情况下,只有一般的预测。
Using analytic expressions, we explore the parameter space for hilltop inflation models with a potential of the form V0 ± m2ϕ2−aϕp. With the positive sign and p>2 this converts the original hybrid inflation model into a hilltop model, allowing the spectral index to agree with the observed value n = 0.95. In some cases the observed value is theoretically favored, while in others there is only the generic prediction .
