A Penn State-led team used advanced lattice quantum chromodynamics and hybrid computational methods to achieve agreement between theory and experiment within half a standard deviation.
Their study, published in Nature, closes a decades-old gap in muon g−2 measurements, eliminating evidence for a possible fifth force and reinforcing the Standard Model to 11 decimal places.
While the findings narrow the search for new physics, they provide the most precise proof yet of quantum field theory, with future experiments still needed to explore remaining possibilities.
How did Europe's first exascale supercomputer help prove a fundamental theory of the universe?
With the top clue for a 'fifth force' gone, where will physicists hunt for new discoveries?
Why did scientists win a major prize for a discovery that a new calculation just erased?
If this new calculation is correct, why does another trusted method still hint at new physics?
Does solving a great mystery by improving math, not discovery, change the future of physics?
A decade of work just proved an old theory right. Was this a triumph or a dead end?
