Getting ready for the muon g-2 release
The muon anomalous magnetic moment (the muon "g-2") is one of the best determined observables in nature. Its measurement at Brookhaven (USA) in the early 2000s, which reached the astonishing experimental precision of 0.5 parts per million, shows an intriguing discrepancy with the similarly precise theoretical prediction of the "Standard Model", the theory that describes all known particles and their interactions through electromagnetic, weak, and strong forces. This is, at present, a discrepancy of 3.7 standard deviations. Wednesday April 7th, the "Muon g-2" collaboration at Fermilab (USA) will present their highly anticipated new measurement of the muon anomalous magnetic moment. If Fermilab confirms Brookhaven's measurement, this could be clear evidence of "new physics" beyond the Standard Model.
