Add Yahoo as a preferred source to see more of our stories on Google. The particle, known as the Ξcc⁺ (Xi‑cc‑plus), is a new type of heavy proton-like particle containing two charm quarks and one down ...

The first-known observations of matter–antimatter asymmetry in a decaying composite subatomic particle that belongs to the baryon class are reported from the LHCb experiment located at the Large ...

Look alive, science fans — a new subatomic particle has just dropped after a 20-year search. Discovered by British researchers at the nuclear research laboratory CERN near Geneva, Switzerland, the ...

Physicists may have yet another fundamental particle left to discover. When physicists at the Large Hardon Collider discovered the Higgs boson back in 2012, they’d found the last missing piece of the ...

Scientists have proposed a new kind of subatomic particle to explain another particle’s mysterious disintegration. The kaon, a special case of meson particle, is made of one quark and one antiquark.

A single subatomic particle from deep space had the same energy as a baseball pitch, and scientists still don’t know how it got here ...

Neutrinos are known for funny business. Now scientists have set a new limit on a quantum trait responsible for the subatomic particles’ quirkiness: uncertainty. The lightweight particles morph from ...

The nature of dark matter is largely unknown, but it is thought to have mass, which influences particle interactions in the universe through gravity. Dark matter may not interact much with visible ...

Muons are getting a move on. In a step toward new types of particle physics experiments, scientists cooled and then accelerated a beam of muons. The subatomic particles, heavy cousins of electrons, ...

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 ...

Scientists from the University of Manchester have played a leading role in the discovery of a new subatomic particle at CERN's Large Hadron Collider (LHC). The particle, known as the Ξ cc ⁺ ...
