Large-Angle Cosmic Microwave Background Anisotropy in an Open Universe in the One-Bubble Inflationary Scenario
Open accessAbstract
We consider an alternative scenario of inflation which can account for a spatially open universe. It is similar to the old inflation in which the bubble nucleation occurs in the sea of the false vacuum, but it differs from the old inflation in that the second slow rollover inflation occurs inside a nucleated bubble. Hence, our observable universe is entirely contained in one nucleated bubble. The significance of the scenario is that apart from a variance caused by model parameters, it gives us a definite prediction on the spectrum of the primordial density perturbations, and hence it is observationally testable. Here we investigate the spectrum of cosmic microwave background anisotropies on large angular scales. We find that the contribution from peculiar modes which never appear in the usual harmonic analysis is significant in the case Ω0 ≲ 0.1.

Each is checked against this paper’s own text: does it say what the citing paper says it does?
In the present case, all three measures mentioned (comoving probability, causal patch, and scale-factor cutoff) give similar predictions.
“however in the present case it turns out that all three measures mentioned above give similar predictions [66,67,68,69].”
From Observable effects of anisotropic bubble nucleation (2010) · cites this paper as [67]
Section III compares CMB predictions for different vacuum states, and Section IV discusses when those predictions differ. Neither addresses whether comoving probability, causal patch, and scale-factor cutoff measures give similar predictions; searches for those measure terms found no relevant passage.

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.
