Description
There is a long standing discrepancy between the Standard Model prediction
for the muon g-2 and the value measured
by the Brookhaven E821 Experiment. At present the discrepancy stands at
about three standard deviations, with
comparable accuracy between experiment and theory. Two new proposals at
Femilab and J-PARC plan to improve the
experimental uncertainty of a factor 4, and there is good motivation to
expect a further reduction of the error from
the theoretical side. I will review the status of the proposal to
Fermilab, E989, and discuss how the goal of 0.14 ppm
on the muon anomaly can be achieved, by collecting more than 21 times the
statistics of the BNL measurement, and
obtaining a factor of 3 reduction in the overall systematic error.
