Physicists from the Muon g-2 experiment have released their third measurement of the muon magnetic anomaly. The final result agrees with their published results from 2021 and 2023 but with a much better precision of 127 parts-per-billion, surpassing the original experimental design goal of 140 parts-per-billion.

Illustration of an ultraperipheral collision where the two lead (208Pb) ion beams at the LHC pass by close to each other without colliding; in the electromagnetic dissociation process, a photon interacting with a nucleus can excite oscillations of its internal structure and result in the ejection of small numbers of neutrons (two) and protons (three), leaving the gold (203Au) nucleus behind.
