No one has ever probed a particle more stringently than this. In a new experiment, scientists measured a magnetic property of the electron more carefully than ever before, making the most precise ...

Magnets of the Tevatron Collider at Fermilab, Illinois. A newly published analysis of data from the Tevatron, which shut down in 2011, shows an unexpectedly high mass for a particle called the W-boson ...

After a decade-long analysis, a collaboration of physicists has made the most precise measurement of the mass of a key particle – and it may unravel physics as we know it. The new measurement differs ...

Our best model of particle physics explains only about 5 percent of the universe. The Standard Model is a thing of beauty. It is the most rigorous theory of particle physics, incredibly precise and ...

The particle in question, known as a sterile neutrino, was supposed to only interact with gravity and have zero interactions ...

Learn about the Standard Model of particle physics and how physicists use it to predict the (subatomic) future. In ancient times, Greeks interested in forecasting the future would voyage on the ...

As a physicist working at the Large Hadron Collider (LHC) at Cern, one of the most frequent questions I am asked is “When are you going to find something?”. Resisting the temptation to sarcastically ...

Diana Parno’s head swam when she first stepped inside the enormous, metallic vessel of the experiment KATRIN. Within the house-sized, oblong structure, everything was symmetrical, clean and blindingly ...

Physicists are exploring whether hidden dimensions and the shape of space could help explain why fundamental particles have ...

The theorized unseen structure of spacetime could also explain of the outstanding questions about the accelerating expansion ...

According to the Standard Model, the leptons and antileptons should all be separate, independent particles from one another. But the three types of neutrino all mix together, indicating they must be ...
