σ(e^+ e^- \to hadrons)$ at low energy: experimental status and prospects for the future. Its influence on $α_{QED}(M^2_{Z})$ and $(g-2)

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/37051In this talk I will review the recent experimental status of $σ(e^+ e^- \to hadrons)$ at $\sqrt{s}<10 GeV$ and the prospects for the future. The influence on $α_{QED}(M^2_{Z})$ and $(g-2)_μ$ is also discussed.5 pages, 2 figures.
