ABSTRA C T Recent tentative findings of non-Gaussian structure in the COBE-DMR data set have triggered renewed attention on candidate models from which such intrinsic signature could arise. In the framework of slow-roll inflation with built-in non-linearities in the inflaton field evolution, we present expressions for both the cosmic microwave background (CMB) skewness and the full angular bispectrumC ‘1‘2‘3 in terms of the slow-roll parameters. We use an estimator for the angular bispectrum… Expand

TLDR
The amplitudes of the perturbations and the power-law slopes of their spectra can be expressed in terms of the value of the potential 50 [ital e]-folds before the end of inflation, as well as the rate of change of its steepness. Expand
