Elementary particle physics reflects the human quest to understand the basic building blocks of nature and the rules that govern the physical world. This quest has led not only to critical scientific ...

Heisenberg’s Uncertainty Principle states that there are limits to how precisely certain pairs of physical properties, like ...

A new measurement of a fundamental particle called the W boson appears to defy the standard model of particle physics, our current understanding of how the basic building blocks of the universe ...

Particle accelerators are often framed as exotic machines built only to chase obscure particles, but they are really precision tools that use electric fields and magnets to steer tiny beams of matter ...

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 ...

At the start of the 20th century scientists had little knowledge of the building blocks that form our physical world. By the end of the century they had discovered not just all the elements that are ...

At every moment, subatomic particles stream in unfathomable numbers through your body. Each second, about 100 billion neutrinos from the sun pass through your thumbnail, and you’re bathed in a rain of ...

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, ...

A committee-supported project or activity that has been completed and for which output dissemination has begun. Its committee has been disbanded and closeout procedures are underway. Elementary ...
