Now let’s continue to understand the recent g-2 result. Last time we briefly touched upon how current loops respond to an external magnetic field, and why electrons and muons fall into this category due to their spin. Now let us sketch how the value is actually related to the spin.... [Read More]

A few of my friends asked me about the recent Fermilab results. We know that recently there is some “anomaly” going on at Fermilab, and the result is statistically significant when combined with the previous measurement from Brookhaven National Laboratory (BNL). This post will be mostly for the background. I... [Read More]
