Abstract

Spacetime-varying coupling constants can be associated with violations of local Lorentz invariance and CPT symmetry. An analytical supergravity cosmology with a time-varying fine-structure constant provides an explicit example. Estimates are made for some experimental constraints.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Varying coupling constants can also be associated with violations of local Lorentz invariance and CPT symmetry.

    “To finish, note that varying coupling constants can also be associated with violations of local Lorentz invariance and CPT symmetry (Kostelecky ´et al. 2003;Bertolami et al. 2004;Gurzadyan et al. 2010).”

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.
