A physical constant’s value shouldn’t depend on how you measure it The Fine Structure Constant may help tell us what's beyond the Standard Model. John Timmer – Apr 13, 2018 11:33 am | 124 ...

At Fermilab, US physicists are refining their measurements of this subatomic particle—which has major implications for the Standard Model.

After six years of experiments, Fermilab finished its measurements last month and announced the latest results Thursday to great international interest from physicists: g-2 = 0.00233184110 +/- 0. ...

The standard model of particle physics has stood the test of time for decades, but now a new measurement of a particle called the W boson could indicate a chink in its armour. Close.
