The muon mismatch was caused by calculation limits, not a new force. Improved methods bring theory and experiment into close agreement.

Combining LaMET with phenomenological modeling using global constraints from SDE can offer accurate state-of-the-art lattice quantum chromodynamics of PDFs, offering a new approach for first-principle ...

A tiny discrepancy in particle physics has loomed for decades as an exciting possible crack in one of science's most successful theories, hinting at unknown forces or quantum objects. Now, an ...

When the results of an experiment don’t match predictions made by the best theory of the day, something is off. Fifteen years ago, physicists at Brookhaven National Laboratory discovered something ...
