The plot shown below shows the most recent calculation of the Standard Model prediction for the muon anomalous magnetic moment compared to the measured value from our experiment (E821). The Standard Model error is dominated by the first order hadronic contribution. M. Davier et. al. (hep-ph/0208177)

  • What is the muon g-2 experiment?

    The muon g-2 experiment at Brookhaven National Lab is making a precise measurment of the anomalous magnetic moment of the muon.

  • Why is this measurment interesting?

    All currently known interactions of elementary particles can be explained by the Standard Model of particle physics. The anomalous magnetic moment of the muon has been calculated to very high precision based on the Standard Model. By making a measurment, then comparing to the theoretical calculation, we are able to test the Standard Model and possibly discover evidence of previously unknown particles and interactions.

  • What part has the University of Minnesota group played in the experiment?

    We have been responsible for the data acquisition system, online monitoring, slow control, and the Position Sensitive Detectors. We have an active analysis group working on the measurement of the muon precession frequency and a seperate analysis to search for a muon electric dipole moment.

  • Are these questions really "frequently asked"?

    Probably not, but "Infrequently Asked Questions" just doesn't have the same ring to it.
