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 ...

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

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 ...

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 ...

Particle physics has always proceeded in two ways, of which new particles is one. The other is by making very precise measurements that test the predictions of theories and look for deviations from ...

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 ...

Physicists have spent decades treating mass as something the universe simply hands to particles, a property encoded in ...

The Standard Model is one of the most well-tested theories in particle physics. But scientists are searching for new physics beyond it. Humans have always sought to understand the essence of the world ...

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