Latest on the muon g-2 from experiment

Abstract

We review the latest experimental achievements on the hadronic cross section measurements at low energy which are of fundamental importance for a precise evaluation of the hadronic contribution to the g-2 of the muon. We also discuss the new proposed muon g-2 experiments, with particular emphasis on E989 at Fermilab which plans to improve the experimental uncertainty by a factor of 4 with respect to the previous E821 experiment at BNL
