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 ...

For the past half century or so, a theory known by the understated name of the Standard Model has dominated the field of particle physics. This theory provides us with a detailed description of the 17 ...

Physicists know that their elegant theoretical description of forces and particles – the Standard Model – must be incomplete, ...

From the outside, the high-speed collisions of atomic nuclei inside particle accelerators like CERN’s Large Hadron Collider (LHC) may seem like they have very little in common with more mundane ...

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 ...

Jason Bono was one of the researchers behind a major scientific moment — when tiny particles unexpectedly unraveled one of the most important and successful theories in physics. Bono, who earned his ...

New research suggests a particle inside an atom can lose mass, offering a fresh look at how matter works at the smallest ...

Physicists have found that an elementary particle called the W boson appears to be 0.1% too heavy — a tiny discrepancy that could foreshadow a huge shift in fundamental physics. The measurement, ...

The Large High Altitude Air Shower Observatory (LHAASO) has detected PeV (1015 eV) gamma-ray emission from a pulsar wind ...

High above Earth, in the thin air of the Tibetan Plateau, a giant observatory ...

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 ...
