Jim and Randy discuss measurements of the anomalous magnetic moment of the muon, as well as what the discrepency between theory and experiment might mean as far as new physics.

4. The Mathematica Notebook mentioned in the first article. You can use this to explore different kinds of beyond the standartd model particles in the way the authors did.
5 Jim mentioned Melvin Schwartz's Principles of Electrodynamics [Amazon], an old textbook that goes into the details of the measurement of the anomalous magnetic moment. Because this is at least the second time I've used it extensively for the podcast, I have made a video, available here describing the book. Fortunately, my phone only had space for a 14 minute video, so I had to shut up about it.

Transcript (Rough Draft)

Sorry! I tried to fix the cover art for this episode, and it got stuck in reprocessing hell. So, it was unavailable for a couple of days.
ReplyDeleteIf you subscribe to the podcast, I hope it didn't show up in your feed a second time! It didn't in my player, but I did receive an email from a secondary source saying that it was newly published after the issue was resolved.
