  • We reconsider several current bounds on the variation of the fine-structure constant in models where all gauge and Yukawa couplings vary in an interdependent manner, as would be expected in unified theories. In particular, we reexamine the bounds established by the Oklo reactor from the resonant neutron capture cross section of ${}^{149}\mathrm{Sm}.$ By imposing variations in ${\ensuremath{\Lambda}}_{\mathrm{QCD}}$ and the quark masses, as dictated by unified theories, the corresponding bound… CONTINUE READING
