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 ...

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 ...

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 ...

An MIT-led team has found that data from “near-misses” at the Large Hadron Collider, long dismissed as background noise, can ...

Scientists have used CERN's Large Hadron Collider (LHC) to uncover what they say is an entirely new type of particle, dubbed ...

In 1930, a young physicist named Carl D. Anderson was tasked by his mentor with measuring the energies of cosmic rays—particles arriving at high speed from outer space. Anderson built an improved ...

CERN’s Large Hadron Collider (LHC) is designed to probe the fringes of known physics, and now the facility has found particles not behaving as predicted. While it’s still early days, the discovery ...

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 ...

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 ...

The muon collider was once dismissed as impossible, but is now gaining steam as the successor to the Large Hadron Collider.

New, precise measurements of already discovered particles are shaking up physics, according to a scientist working at the Large Hadron Collider. By Roger Jones / The Conversation Published May 9, 2022 ...
