Now, one might think that in modern physics, the magnetic moment of a nucleus and the shielding effect of the electron shell could be calculated accurately. However, this is not the case ...

Alex Keshavarzi digs into the showdown between two competing Standard Model predictions of the muon, which may reveal undiscovered particles hiding in the vacuum ...

What happens in that precise moment is what Hagen and his colleagues ... measure used in nuclear physics to describe the magnetic behavior of a nucleus. But in 2011, nearly three decades later ...
