For a few years, one of particle physics’ most unsettling numbers seemed to be pointing somewhere strange. The trouble ...

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 ...

The new calculation, made at the Large Hadron Collider (LHC) near Geneva, could help solve a niggling mystery about this ...

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 ...

Measurement of W boson particle mass confirms Standard Model of physics and reignites the search for other particles.

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 ...

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 ...

Javier Duarte kicked off his scientific career by witnessing the biggest particle physics event in decades. On July 4, 2012, scientists at the laboratory CERN near Geneva announced the discovery of ...

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 ...
