Therefore we obtain the primordial curvature perturbation as

This is of the same order of magnitude as the primordial curvature pertur- bation that is produced by the “end of inflation” mechanism, Eqs. (4.59) and (4.63). 

## 4.5.1 Non-Gaussianity 

As with the “end of inflation” mechanism scenario, we will consider what is termed local non-Gaussianity, which for the bispectrum corresponds to the “squeezed” configuration of the momenta triangle, in that the magnitude of
