Muons Defy Standard Model: New Physics Effects Suggested

[Guybrush Threepwood]

Muons continue to defy Standard Model

"The recent g-2 result strengthens the case for new physics effects, with supersymmetry a leading candidate, but it is by no means definitive," says William Marciano, a theorist at Brookhaven. "Continued scrutiny of theory and further running of the experiment are imperative."

It's still not at $3\sigma$...

Nevertheless, it's quite interesting and exciting.

I've been watching these developments since the earlier Brookhaven announcement. What I've seen so far is that the calculation of this quantity is still in a very unsettled state. Depending on whose doing it, the results can be anywhere from a fraction to several standard deviations off from the experiment. Until the theoreticians can come to some sort of agreement, the jury is still out.
