Lattice determination of the muon's anomalous magnetic moment
On 4/7/2021 the Fermilab announced the result of a two decade long investigation to determine the magnetic moment of the muon. By tradition, data-driven theoretical methods have been used for 50 years to calculate this magnetic moment. But, interestingly, in the last 20 years growing discrepancies were noted between theoretical and experimental findings. In the literature, the result obtained by using the data-driven method is called the “consensus value" - and it is 4.2 sigma away from the combined experimental result. This 4.2-sigma discrepancy was interpreted by many physicists as a sign for new physics with a new and unknown force - and hundreds of papers appeared in the last few months…
