A philosopher has put forward an argument for rethinking how particles are defined within the standard model of particle ...

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 ...

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 ...

Despite its tremendous success in predicting the existence of new particles and forces, the standard model of particle physics, designed over 50 years ago to explain the smallest building blocks of ...

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 ...

If photons possess more quantum states than expected, it would overhaul our understanding of all particle physics – and now physicists have identified a way to test this radical idea in an experiment.

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 ...

Particle and high energy physics seeks to understand the fundamental constituents of matter and the interactions that govern them across the smallest distance scales and highest energies. The Standard ...

Physicists have found that an elementary particle called the W boson appears to be 0.1 percent too heavy—a tiny discrepancy that could foreshadow a huge shift in fundamental physics. The measurement, ...

Scientists working at CERN’s Large Hadron Collider may be seeing the strongest hints yet of physics beyond the Standard Model — the decades-old theory that explains the fundamental particles and ...

Physicists have found that an elementary particle called the W boson appears to be 0.1% too heavy — a tiny discrepancy that could foreshadow a huge shift in fundamental physics. The measurement, ...

Gauge theories underpin the modern understanding of fundamental interactions by invoking local symmetry principles. The prototypical non-Abelian Yang–Mills framework generalises Maxwell’s ...
