Scientists working on Fermilab's Muon g-2 experiment released the world's most precise measurement yet of the magnetic moment of the muon, bringing particle physics closer to the ultimate showdown ...

Two independent lines of evidence from the world’s most powerful particle experiments are converging on the same ...

Something odd is happening deep inside the data streams from CERN’s Large Hadron Collider. A set of “forbidden” patterns in how unstable particles decay, combined with rare Higgs events and a ...

Physicists now have a brand-new measurement of a property of the muon called the anomalous magnetic moment that improves the precision of their previous result by a factor of 2. An international ...

The experiment's third and final result, based on the last three years of data, is in perfect agreement with previous results, further solidifying the experimental world average. Scientists working on ...

After years of confusion, a new study confirms the proton is tinier than once thought. That enables a test of the standard model of particle physics.

Imagine trying to prove that 1+1=2, but when you do the calculations, it turns out that the result is off by 0.1%. That scenario is similar to the riddle that’s facing physicists worldwide as they try ...

Physicists in Germany have carried out the most accurate measurement to date of the width of the proton. By examining a previously unexplored energy-level transition in the hydrogen atom, Lothar ...
