Short-Distance-Free Leptonic g−2
Abstract
We note that the hadronic contributions to ae and aμ are strongly correlated, which potentially allows one to reduce the uncertainties associated with higher-energy contributions (and address the current discrepancy between lattice and data-driven evaluations) by improved measurements of ae and the fine-structure constant.
