Description

I will discuss the use of the so-called relativistic sum rules for the precise extraction of the charm-quark mass and the strong coupling, $\alpha_s$, from experimental data for $\sigma(e^+e^- \to {\rm hadrons})$. I will focus on the role of the data from $e^+e^-$ colliders and in particular on the combination of data sets and the required algorithm used in state-of-the-art analyses, such as the above mentioned sum rules and the dispersive approach to $g-2$ of the muon.
