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 ...

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

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 ...

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 ...

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 ...

Two independent lines of evidence from the world’s most powerful particle experiments are converging on the same uncomfortable conclusion: something is producing signals that the Standard Model of ...

When fundamental particles are heavier or lighter than expected, physicists' understanding of the universe can tip into the ...

CHICAGO (CBS) -- A powerful new particle accelerator that could be set up at Fermilab, a telescope to observe the oldest light in the universe, and research to learn more about mysteries such as dark ...

A subatomic particle long predicted by theorists has finally been observed, ending a decades-long wait in physics. Named Ξcc+ ...

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 ...

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 ...
