Particle accelerators reveal the heart of nuclear matter by smashing together atoms at close to the speed of light. The high-energy collisions produce a shower of subatomic fragments that scientists ...

A subatomic particle long predicted by theorists has finally been observed, ending a decades-long wait in physics. Named Ξcc+ ...

GENEVA — The physics lab that’s home to the world’s largest atom smasher announced on Tuesday the observation of three new “exotic particles” that could provide clues about the force that binds ...

Physicists have shown that particles produced in collimated sprays called jets retain information about their origins in subatomic particle smashups. Physicists at the U.S. Department of Energy's (DOE ...

"Hearst Magazines and Yahoo may earn commission or revenue on some items through the links below." New research shows that protons contain intrinsic charm quarks. This is despite the fact that ...

When an energetic quark or gluon gets knocked free during a proton-proton collision, this free "parton" first generates a shower of other partons, which then "fragment" to form hadrons (h) such as ...

Over a century ago, Ernest Rutherford discovered the proton by splitting the atom in a laboratory in Manchester. Today, researchers based in Manchester have discovered a new particle that Rutherford ...
