g-2 of the muon is an important observable in particle physics that can be used to discover or constrain physics beyond the Standard Model. The measured value of muon g-2 currently shows a deviation of 3.7 sigma from its predicted value. New results from Fermilab on muon g-2 are expected in the near future.


Here, we start with an explanation of what g-2 of the muon is. g-2 of the muon is closely related to the muon magnetic moment. However, magnetic moments occur in systems other than elementary particles. Here, we start with a discussion of a magnetic moment in an example from electromagnetism. We then point out that particles like the electron and muon have charge and spin, and that it thus may not be surprising to find that they also have magnetic moments.



In Part II, we'll talk about how the magnetic moment of the muon fits into particle physics.
