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 ...

The discovery of the Higgs Boson in 2012 represented a major turning point for particle physics marking the completion of what is known as the standard model of particle physics. Yet, the standard ...

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 ...

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 ...

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 ...

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 ...

The standard model of particle physics may be due for a philosophical remodel, including rethinking what qualifies each of its particles to count as a particle to begin with. Whether a particle is ...

In July 2012, physicists at the Large Hadron Collider (LHC) in Europe triumphantly announced the discovery of the Higgs boson, the long-sought linchpin of the subatomic world. Interacting with Higgs ...

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

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, ...

A weird force that skirts traditional physics norms has helped erase a smudge on the foundations of particle physics. It’s a phenomenon called the “neutrino force,” by which neutrinos could ...
