A year after their final muon magnetic anomaly announcement, the Muon g-2 collaboration today announced a new measurement of a different property of the muon: its electric dipole moment. Based on an analysis of 25% of Fermilab’s experimental data, this is the most sensitive direct search for a muon EDM ever accomplished. It is the first direct search for the muon EDM done at the U.S. Department of Energy’s Fermi National Accelerator Laboratory and only the third search globally in the last 50 years. Searches for EDMs play a vital role in particle physics; detecting an EDM could be key to better understanding the matter-antimatter asymmetry required to explain the universe we see around us. This new result shows that if a muon EDM exists, it must be smaller than what the Muon g-2 experiment can currently detect. Fermilab has hosted the Muon g-2 experiment and collaboration since 2008. The experiment is made up of a 50-foot-diameter superconducting magnetic storage ring repurposed from an earlier version of the experiment at DOE’s Brookhaven National Laboratory, which concluded in 2001. The Fermilab experiment improves upon the Brookhaven version in numerous ways, enabling more precise measurements. The Muon g-2 experiment sends a beam of muons - technically their antimatter counterparts, anti-muons or positive muons - into the storage ring, where they circulate hundreds of times at nearly the speed of light before they decay. Detectors lining the ring observe the decay products and allow scientists to determine how fast the muons are precessing, or wobbling, in the presence of a magnetic field. The precession speed is related to a property of the muon called the magnetic dipole moment, represented by the letter g. Theory predicts that g should be slightly larger than 2. The electric dipole moment is a property that describes the
