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 ...

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 ...

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, ...

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 ...

Particle physics is a research area focused on the fundamental constituents of matter and radiation and the interactions governing them, typically described by quantum field theories such as the ...

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 ...

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, ...

His work paved the way for the discovery of the Higgs boson, which explained how particles acquire mass, solving one of the ...
