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, ...

The muon mismatch was caused by calculation limits, not a new force. Improved methods bring theory and experiment into close ...

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 ...

A neglected force produced by neutrinos and other particles helps atomic physics measurements align with predictions of the standard model.

A tiny discrepancy in particle physics has loomed for decades as an exciting possible crack in one of science’s most ...

Theories of quantum mechanics predict that some particles can exist in superpositions, which essentially means that they can ...

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 ...

A tiny discrepancy in particle physics has loomed for decades as an exciting possible crack in one of science's most successful theories, hinting at unknown forces or quantum objects. Now, an ...

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 ...

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 ...
