扩展的慢滚条件和原始涨落:多重标量场和广义引力

Extended Slow-Roll Conditions and Primordial Fluctuations: Multiple Scalar Fields and Generalized Gravity

Takeshi Chiba, Masahide Yamaguchi

摘要:

作为我们以前的研究的延伸,我们推导出多个标量场的慢滚条件,这是非最小耦合重力和广义引力理论的形式$f(ϕ,R)$。本文给出了标量/张量扰动谱指数的简单公式。

英文摘要:

As an extension of our previous study, we derive slow-roll conditions for multiple scalar fields which are non-minimally coupled with gravity and for generalized gravity theories of the form $f(ϕ,R)$. We provide simple formulae of the spectral indices of scalar/tensor perturbations in terms of the slow-roll parameters.
