资源简介：
We calculate the squeezed limit of the bispectrum produced by inflation with multiple light fields. To achieve this we allow for different horizon exit times for each mode and calculate the intrinsic field-space three-point function in the squeezed limit using soft-limit techniques. We then use the delta N formalism from the time the last mode exits the horizon to calculate the bispectrum of the primordial curvature perturbation.
