A new estimation of the strength of the magnetic field around the muon a sub-atomic particle similar to, but heavier than, an electron closes the gap between theory and experimental measurements, bringing it in line with the standard model that has guided particle physics for decades.
A paper describing the research by an international team of scientists appears April 8, 2021 in the journal
Nature.
