What happens when the smallest building blocks of matter refuse to play by the rules of traditional physics? For decades, atomic nuclei have posed a stubborn puzzle: at low energies, they appear as ...

Trillions of times smaller than a grain of sand and smaller than an atomic proton or neutron, quarks are among the smallest particles in the universe. They are essentially building blocks for ...

NEWPORT NEWS, VA – Inside the nucleus of the atom, the building blocks of matter are anything but static. Individual particles are in a constant state of energetic motion, like dancers on a dance ...

Observational first: physicists have used the ATLAS experiment at CERN to observe the production of top-quark and photon pairs. (Courtesy: CERN) For the first time, particle physicists have observed ...

New research suggests a particle inside an atom can lose mass, offering a fresh look at how matter works at the smallest scale.

Imagine you have a microscope that would let you see a single atom up close. Let's say it's a hydrogen atom, the smallest kind. Zoom in past the single electron orbiting at the outskirts, and you'll ...

Scientists from the CMS collaboration at CERN have measured the speed of sound in the quark-gluon plasmas with record precision, a key step to understanding how matter behaved in the very early ...
