Theta-Induced Electric Dipole Moment of the Neutron via QCD Sum Rules
Open accessAbstract
Using the QCD sum rule approach, we calculate the electric dipole moment of the neutron induced by a vacuum $\ensuremath{\theta}$ angle to approximately $40%$-- $50%$ precision, ${d}_{n}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1.2\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}16}\overline{\ensuremath{\theta}}e\mathrm{cm}$. Combined with the new experimental bound, this translates into the limit $|\overline{\ensuremath{\theta}}|<6\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}10}$.

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.
