Description

We note that the hadronic contributions to $a_e$ and $a_\mu$ are strongly correlated, which potentially allows to reduce the uncertainties associated with higher energy contributions (and address the current discrepancy between lattice and data-driven evaluations) by improved measurements of a_e and the fine-structure constant.
