多场暴胀中标量谱指数的运行

Running of scalar spectral index in multi-field inflation

Jinn-Ouk Gong

摘要:

我们计算了一般多场慢卷暴胀中标量谱指数的变化。通过在视界穿越时刻引入明确的动量依赖关系,我们可以直接找到运行。同时,我们可以区分准de Sitter背景和超视界演化的场涨落的贡献。

英文摘要:

We compute the running of the scalar spectral index in general multi-field slow-roll inflation. By incorporating explicit momentum dependence at the moment of horizon crossing, we can find the running straightforwardly. At the same time, we can distinguish the contributions from the quasi de Sitter background and the super-horizon evolution of the field fluctuations.
