What is g-2 of the Muon? (Part II)

This is a video in our Miniseries on g-2 of the Muon:    • Miniseries on g-2 of the muon   In the previous video, What is g-2 of the Muon? (Part I),    • What is g-2 of the muon?  (Part I)   we looked at what a magnetic moment was from the perspective of electromagnetism. Here, we look at how the magnetic moment of the muon or the electron fits into the realm of particle physics. We briefly discuss Larmor precession, which is important in the experimental determination of g-2. We then point out that the magnetic moment of the muon (or electron) relates to how it interacts with an electromagnetic field. This implies that it also relates to how it interacts with the photon. We mention Dirac's original calculation giving g=2 and then look at the largest correction to this result, the Schwinger term. We'll look at additional corrections to the anomalous magnetic moment in the Standard Model in the next video.
