Description

The precise Brookhaven measurement of the anomalous magnetic moment of the muon, or muon g-2, exhibits a long-standing discrepancy with the Standard Model (SM) prediction. As a result of the improved accuracy of the SM determination, this discrepancy has increased in recent years reaching at present 3.7 standard deviations. The first result from the Muon g-2 experiment at Fermilab will be unveiled on Wednesday April 7 at 5pm (Italian time). This highly anticipated new result may confirm or refute that discrepancy. If confirmed, it could be clear evidence of new physics beyond the SM.

In anticipation of Fermilab's result, Massimo will review the present status of the muon g-2 SM prediction (and why we should trust it), Stefano will tell us how he managed to compute the electron and muon g-2 at four-loop in QED, and Pierpaolo will review the theory progress for MUonE, a recent proposal for a new experiment at CERN to provide a new direct determination of the leading hadronic contribution to the muon g-2. Finally, Paride will review new physics interpretations of the present muon g-2 discrepancy (of course, this might be his last talk on this topic).
