- W2061401085 abstract "We reconsider the ${}^{187}mathrm{Re}$ bound on the variation of the fine-structure constant. We combine the meteoritic measurement with several present-day lab measurements to firmly establish the quantitative upper limit to the time variation over the age of the solar system. We find that the relative change of the fine-structure constant between its present value and $ensuremath{alpha}$ of $ensuremath{sim}4.6mathrm{Gyr}$ ago is consistent with zero, $ensuremath{Delta}ensuremath{alpha}/ensuremath{alpha}=[ensuremath{-}8ifmmodepmelsetextpmfi{}8(1ensuremath{sigma})]ifmmodetimeselsetexttimesfi{}{10}^{ensuremath{-}7}.$ We also rederive this bound in models where all gauge and Yukawa couplings vary in an interdependent manner, as would be expected in unified theories." @default.
