SPECIAL DATE NPA Zoom Seminar, David Kawall, U Mass, “An anomaly in an anomaly? First results from the Fermilab Muon g-2 Experiment”

The Fermilab muon g-2 experiment just released its first measurement of the positive muon magnetic moment anomaly, a_mu = (g_mu-2)/2 to an accuracy of 0.46 ppm. The anomaly a_mu is of interest since it can be predicted with impressive precision and its value is sensitive, via quantum corrections, to the interactions of the muon with the other particles of the Standard Model. Comparison of measurement results and theoretical predictions tests the completeness of the Standard Model, and a significant discrepancy would indicate the need for new physics. Details of the Fermilab experiment and its first result will be presented, along with a comparison with the theory and future prospects.
