From RTS (Swiss Broadcasting Corporation), Sept. 7, 2023: Fermilab’s August 10 announcement indicated the muon does not behave as theory predicts. Professor Tobias Golling, from the particle physics department at the University of Geneva, explains in a video that there are two possibilities to explain the observed discrepancy.

What is the future of muon colliders? Particle physicists are seeing less challenges in their development than ten years go and are pushing for a muon collider as the P5 report comes out this fall.
A large number of scientists are working on improving the Standard Model prediction of the value of muon g-2 using new data and new lattice calculations. By measuring and calculating this number to ultra-high precision, scientists can test whether the Standard Model is complete.
