Fermilab's Muon g-2 Experiment hints at Physics beyond the Standard Model
UMass Physics Professor David Kawall and his group, grad student David Kessler and former postdocs David Flay and Jimin George, are part of the Muon g-2 collaboration at Fermilab that has just published a long-awaited measurement of the magnetic moment anomaly of the muon. Accurate to 8 significant figures, and consistent with a previous measurement, the result differs from a prediction of the Muon g-2 Theory Initiative, and most significantly, hints at the influence of long-sought new physics beyond the standard model. UMass professor Toichiro Kinoshita and collaborators carried out some of the most precise calculations in all of physics required in the predictions. The experiment continues to take and analyze data, and should have updated results within a year.
