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 ...

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 ...

An obscure theory of elementary particles proved to be key to China’s re-emergence as a scientific nation after the Cultural ...

The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

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 ...

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 ...

NPR's Ayesha Rascoe speaks to Esra Barlas Yücel, a researcher at University of Illinois at Urbana-Champaign, about Fermilab's most precise measurements of the muon particle's magnetic wobble. It's ...

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 ...

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 ...

Physicists at the world's largest particle accelerator have made a first-of-its-kind discovery about antimatter that could help solve one of the universe's biggest mysteries. The discovery — made at ...

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 ...
