Standard Model

From the Observador (Portugal), April 18, 2021: The Muon g-2 experiment confirmed a small discrepancy previously detected between the measured values and those calculated by the most advanced theory we have with the probability that this measure is a statistical error is 1 in 100,000.

From Reccom Magazine, April 13, 2021: After decades of speculation, a Fermilab experiment showing an unexplained discrepancy from the Standard Model was raised to a confidence level of 4.2 sigma.

A super-precise experiment at Fermilab is carefully analyzing every detail of the muon’s magnetic moment. The Fermilab Muon g-2 collaboration has announced it will present its first result at 10 a.m. CDT on April 7.
