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 ...

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 ...

The so-called muon anomaly, first seen in an experiment at Brookhaven National Laboratory in 2001, hasn’t budged. For 20 years, this slight discrepancy between the calculated value of the muon’s ...

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 ...

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 ...

CERN’s calculation of the W boson’s mass agrees with theory, contradicting a previous anomaly that had raised the possibility of new physics. Particle’s surprise mass threatens to upend the standard ...

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 ...

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 ...

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 ...

The W boson, one of the tiniest, most elementary particles in the known universe is causing a big ruckus in the field of particle physics. According to the Standard Model, W bosons (together with ...

The particles and antiparticles of the Standard Model obey all sorts of conservation laws, with fundamental differences between fermionic particles and antiparticles and bosonic ones. The final piece ...
