2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/41087We present a summary of the results of two recent precise calculations of the muon anomalous magnetic moment ($g_μ-2$) and the electromagnetic coupling on the $Z$ ($\barα_{\rm Q.E.D.}(M^2_{Z})$). The main sources of uncertainty are underlined.6 pages, 2 figures, To appear in the Proceedings of the Budapest 2001 EPS HEP ConferenceHigh Energy Physics - PhenomenologyPrecision Determination of the Muon $g_μ-2$ and $\barα_{\rm Q.E.D.}(M^2_{Z})$text
