I read through an entire article about progress in computing this "g-2" value (and defining and introducing that concept), how we were able to do a bunch of math to predict a g-2 value for the electron that turned out amazingly accurate, how the experimental measurement of g-2 for the muon is getting narrowed down, and how the observed value is anomalous and hard to explain.
But I didn't see a claim as to what the value is. I saw a graph with very fuzzy lines and print and a notation on the x-axis that gives me basically no idea of what that 20 point something value means or how it compares to the electron result.
Actually, I guess it didn't give a value for the electron, either:
> The g-2 factor for the electron has now been calculated up to a tiny corrective factor
I interpret that as meaning that the "tiny value" is uncertainty in the electron g-2... ?
