Physicists have long relied on the idea that electrons behave like tiny particles zipping through materials, even though ...

The Large Hadron Collider (LHC) sparked worldwide excitement in March as particle physicists reported tantalizing evidence for new physics — potentially a new force of nature. Now, our new result, yet ...

New results from the MicroBooNE experiment rule out the existence of a sterile neutrino, reshaping how scientists think about long-standing neutrino anomalies. After many years of investigation, resea ...

Physicists have spent decades treating mass as something the universe simply hands to particles, a property encoded in equations rather than explained from first principles. A new proposal argues that ...

A subatomic particle called the muon is wobbling far more than leading physics models can explain. Its unusual behavior could be evidence of a fifth force of nature or a new dimension. Scientists ...

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 ...

Steven Weinberg ’54, the theoretical physicist whose Nobel prize-winning work transformed scientists’ understanding of fundamental forces, died on July 23. He was 88. “[His work] is basically the ...

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 ...

Harry Cliff is employed by the University of Cambridge, is a member of the LHCb collaboration and receives funding from STFC. The Large Hadron Collider (LHC) sparked worldwide excitement in March as ...
