多场扰动的协方差、伪SUSY和f_NL
The covariance of multi-field perturbations, pseudo-susy and f_NL
摘要:
我们重新考虑多分量标量的宇宙学扰动理论,在场空间中加强协方差,并确保物理观测独立于场的重新定义。我们使用的形式主义来澄清文献中的一些问题,并使用伪超对称性,以获得精确的表达式的条款的利益。
英文摘要:
We reconsider cosmological perturbation theory for multi-component scalars, enforcing covariance in field-space, and ensuring that phyical observations are independent of field re-definitions. We use the formalism to clarify some issues in the literature, and use pseudo-supersymmetry to derive exact expressions for terms of interest.
