Abstract

Usually inflation ends either by a slow rolling of the inflation field, which gradually becomes faster and faster, or by a first-order phase transition. We describe a model where inflation ends in a different way, due to a very rapid rolling ("waterfall") of a scalar field $\ensuremath{\sigma}$ triggered by another scalar field $\ensuremath{\varphi}$. This model looks like a hybrid of chaotic inflation with $V(\ensuremath{\varphi})=\frac{{m}^{2}{\ensuremath{\varphi}}^{2}}{2}$ and the usual theory with spontaneous symmetry breaking with $V(\ensuremath{\sigma})=\frac{1}{4\ensuremath{\lambda}}{({M}^{2}\ensuremath{-}\ensuremath{\lambda}{\ensuremath{\sigma}}^{2})}^{2}$. The last stages of inflation in this model are supported not by the inflaton potential $V(\ensuremath{\varphi})$ but by the "noninflationary" potential $V(\ensuremath{\sigma})$. Another hybrid model to be discussed here uses some building blocks from extended inflation (Brans-Dicke theory), from new inflation (phase transition due to a nonminimal coupling of the inflaton field to gravity), and from chaotic inflation (the possibility of inflation beginning at large as well as at small $\ensuremath{\sigma}$). In the simplest version of this scenario inflation ends up by slow rolling, thus avoiding the big-bubble problem of extended inflation.

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.
