THE HAPPENING WORLD: It's Magnetic Moment of the Muon Day!
Fermilab reports precision measurements which strengthen the case for physics beyond the standard model (anomalous magnetic moment of the muon).
We’re thrilled to announce that the first results from Fermilab’s Muon g-2 experiment strengthen evidence of new physics! #gminus2https://t.co/tUx4ojzIps pic.twitter.com/t1ufui2Mwu

And on the same day, a computational quantum chromodynamics group reports that previous theoretical calculations were incorrect and that a recalculation from first principles is consistent with the experimental results.
Rather different takes on new muon g-2 measurement:

4.2 deviation from Standard Model (SM) prediction: https://t.co/IGEnG5PQ8r
vindicates SM, after better QCD calculation (done pre-announcement): https://t.co/M3uqedxQoD
my take, for now: ?
