p-nflation中的标量扰动:3-形式情形

Scalar perturbations in p-nflation: the 3-form case

Cristiano Germani, Alex Kehagias

摘要:

我们计算了3-型暴胀的标量扰动的原始谱,发现曲率扰动在晚期衰减。因此,虽然一个非最小耦合的大质量3型场可能在早期驱动暴胀,但它应该得到其他场的帮助,以便重现所观察到的CMB天空的温度波动。

英文摘要:

We calculate the primordial spectrum of scalar perturbations of the 3-form inflation and we find that the curvature perturbations decay at late times. As as result, although a non-minimally coupled massive 3-form field may drive inflation at early times, it should be assisted by other fields in order to reproduce the observed temperature fluctuations of the CMB sky.
