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

TL;DR

This paper reviews recent experimental measurements of the cross section for electron-positron annihilation into hadrons at energies below 10 GeV, discussing their impact on fundamental constants like the fine-structure constant at the Z boson mass and the muon g-2 anomaly, and explores future prospects.

Contribution

It provides an updated overview of experimental data on hadronic cross sections at low energies and discusses their implications for precision tests of the Standard Model and future experimental directions.

Findings

Recent measurements of +e- d7 hadrons cross section at a0<10 GeV

Impact of these measurements on _{QED}(M^2_{Z}) and _{g-2}(b0)

Future experimental prospects for improving these measurements

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.
