Abstract

We describe a new efficient mechanism of reheating. Immediately after rolling down the rapidly moving inflaton field $\ensuremath{\varphi}$ produces particles $\ensuremath{\chi},$ which may be either bosons or fermions. This is a nonperturbative process which occurs almost instantly; no oscillations or parametric resonance is required. The effective masses of the $\ensuremath{\chi}$ particles may be very small at the moment when they are produced, but they ``fatten'' when the field $\ensuremath{\varphi}$ increases. When the particles $\ensuremath{\chi}$ become sufficiently heavy, they rapidly decay to other, lighter particles. This leads to an almost instantaneous reheating accompanied by the production of particles with masses which may be as large as ${10}^{17}--{10}^{18} \mathrm{GeV}.$ This mechanism works in the usual inflationary models where $V(\ensuremath{\varphi})$ has a minimum, where it takes only a half of a single oscillation of the inflaton field $\ensuremath{\varphi},$ but it is especially efficient in models with effective potentials slowly decreasing at large $\ensuremath{\varphi}$ as in the theory of quintessence.

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.
