Muon g-2 has begun its second run to search for hidden particles and forces. Muon g-2 collaborators have performed upgrades to improve the experiment’s precision and increase the amount of data it generates. As the experiment starts up again, scientists expect to make the world’s most precise measurement of the muon’s anomalous magnetic moment, which could tell us whether additional, undiscovered particles exist in the universe.

From Frontline, July 19, 2018: The Indian magazine gives an overview of the Muon g-2 experiment.

From Argonne National Laboratory, April 19, 2018: Scientists from Argonne National Laboratory and Fermi National Accelerator Laboratory, along with collaborators from over 25 other institutions, are recreating a previous experiment with much higher precision.
