摘要
The dominant contribution to the primordial curvature perturbation may be generated at the end of inflation. Taking the end of inflation to be sudden, formulae are presented for the spectrum, spectral tilt and non-Gaussianity. They are evaluated for a minimal extension of the original hybrid inflation model.
