Re/Os constraint on the time-variability of the fine-structure constant

High Energy Physics - Phenomenology 2009-11-10 v2

Abstract

We argue that the accuracy by which the isochron parameters of the decay 187Re187Os^{187}{\rm Re}\to ^{187}{\rm Os} are determined by dating iron meteorites may not directly constrain the possible time-dependence of the decay rate and hence of the fine-structure constant α\alpha. From this point of view, some of the attempts to analyze the Oklo constraint and the results of the QSO absorption lines are re-examined.
