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

Abstract

In this talk I will review the recent experimental status of $\sigma(e^+ e^- \to hadrons)$ at $\sqrt{s}<10 GeV$ and the prospects for the future. The influence on $\alpha_{QED}(M^2_{Z})$ and $(g-2)_{\mu}$ is also discussed.
