A lower bound on the right-handed neutrino mass from leptogenesis
Open accessAbstract
Abstract In the see-saw model, the baryon asymmetry of the Universe can be generated by the decay of the lightest right-handed neutrino, νR. For a hierarchical spectrum of right-handed neutrinos, we show that there is a model independent upper bound on the CP asymmetry produced in these decays: ϵ m ν 3 = Δm 2 atm and the νR are produced thermally, then leptogenesis requires a reheat temperature of the Universe Treh>MνR>108 GeV. Reasonable estimates of νR production and the subsequent washout of the asymmetry, as made by Buchmuller and Plumacher, imply MνR>109 GeV, and Treh>1010 GeV. Implications for the gravitino problem are also discussed.

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.
