  • The size of the bispectrum during single-field, slow-roll inflation is related to the spectral tilt of the power spectrum and is constrained to be small.

    “For instance, it is known that the size of the bispectrum during single-field, slow-roll inflation is related to the spectral tilt of the power spectrum and is thus constrained to be small [5].”

    From Non-Gaussianities in two-field inflation (2006) · cites this paper as [5]

  • The adiabatic nonlinear parameter can be expressed as a consistency relation between observables.

    “Note that, using Eqs. (62) and (28) for the adiabatic case, this can be expressed as a consistency relation between observables [5],”

    From Non-Gaussianities in two-field inflation (2006) · cites this paper as [5]

  • In the limit t_c → t_*, the nonlinear parameter for purely adiabatic perturbations in the two-field case coincides with the single field case result.

    “which coincides with the single field case result [5, 36].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
