(credit: Cindy Arnold/Fermilab) The Muon g-2 experiment (pronounced “gee minus two”) is designed to look for tantalizing hints of physics beyond the Standard Model of particle physics. It does this by measuring the magnetic field (aka the magnetic moment) generated by a subatomic […]

Unstable helium adds a limit on the ongoing saga of the proton’s size

(credit: Paul Scherrer Institut) Physicists, who dedicate their lives to studying the topic, don’t actually seem to like physics very much, since they’re always hoping it’s broken. But we’ll have to forgive them; finding out that a bit of […]
