>The task before the Muon g-2 Theory Initiative is to solve these dilemmas and update the 2020 data-driven SM prediction. Two new publications are planned.

Essentially all of the theory research (specifically, lattice QCD calculations) since the previous white paper in 2020 have been conducted blinded, and at any rate, the deadline to be included in the theory average has already passed. It would take an act of extraordinary brashness to fudge the numbers now.

Enjoyed reading this and thank you for sharing. Anyone know what are inside those tubes? Thinking to create this with a few younger ones and want to understand any risks should those tube breaks and something escapes.

You're not where you think you are.

> However, these calculations did not take into account the effects of “radiative corrections” – the continuous emission and re-absorption of short-lived “virtual particles” (see box) by the electron or muon – which increases g by about 0.1%.

Our universe is a subtle mess.

But if you observe the observation, does it change both obervations? or just yours? ( Im kiddin ).

FermiLab is doing some great amazing work.
