The Muon g-2 collaboration at Fermilab (Chicago) has just released a measurement of the anomalous magnetic moment of the muon, with an unprecedented precision: 460 parts per billion.
The INFN group at the Department of Physics of the University of Roma Tor Vergata was among the proponents of the Italian participation in the experiment, since 2013. The group participated in all phases of assembly, calibration and data acquisition of the experiment. The group contributed directly to the data analysis to extract the frequency of anomalous oscillation and in the determination of the systematic uncertainties associated, which are key ingredient in the measurement.
