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 ...

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 ...

Over time, particle physics and astrophysics and computing have built upon one another’s successes. That coevolution continues today. In the mid-twentieth century, particle physicists were peering ...

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 ...

Britain is preparing to cancel its contribution to one of the Large Hadron Collider's next major upgrades.

Over a century ago, Ernest Rutherford discovered the proton by splitting the atom in a laboratory in Manchester. Today, ...

Scientists are on the trail of a mysterious five-particle structure that could challenge one of the biggest theories in physics: string theory. This rare particle—never seen before and predicted not ...

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 ...

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 ...
