Muon g-2

Posted on 08/04/2021 by Jon Butterworth

Obviously the big thing this week is the new measurement of the anomalous magnetic moment of the muon, at Fermilab. I’ve written about this experiment a few times before, see these articles. I haven’t had time to write anything about … Continue reading →

A growing anomaly

Posted on 23/03/2021 by Jon Butterworth

The LHCb experiment at the CERN Large Hadron Collider (LHC) today released an update of a measurement that many of us physicists have been keeping a close eye on for quite some time. At the Cosmic Shambles Network
