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 ...

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 ...

A new theory suggests the universe’s greatest secrets are hiding in a “zeptouniverse” that’s ready to be explored—without ...

CHICAGO (CBS) -- A powerful new particle accelerator that could be set up at Fermilab, a telescope to observe the oldest light in the universe, and research to learn more about mysteries such as dark ...

Physicists have spent decades treating mass as something the universe simply hands to particles, a property encoded in equations rather than explained from first principles. A new proposal argues that ...

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 ...

Once a surprise to physicists, these particles are useful tools inside and outside the realm of particle physics. Every minute, countless muons rain down from space, passing through ...

An experimental technique that started life in nuclear and particle physics is now being used to measure chemical reactions inside the human body and to help diagnose cancer and heart disease in ...

A hidden link has been found between two seemingly unrelated particle collision outcomes. It’s the latest example of a mysterious web of mathematical connections between disparate theories of physics.
