Nearly every object we interact with in our lives has a mass, but where does this mass come from? Modern physics says matter ...

Researchers investigated how the η′ meson behaves inside atomic nuclei and found evidence that it may form bound states known as η′-mesic nuclei. Using high-energy particle experiments and ...

An international research team has found evidence of the existence of an exotic atomic nucleus state in an experiment at the ...

Deep inside every atom lies a restless world of quarks and gluons—the tiny building ...

Particle accelerators reveal the heart of nuclear matter by smashing together atoms at close to the speed of light. The ...

Physicists working at Germany’s GSI Helmholtz Centre have found the first experimental hints that an unusually heavy subatomic particle, the eta-prime meson, can bind to an atomic nucleus. If ...

The University of California admitted last week (after too many garbled rumors in the press) that it had created the first man-made meson. U.C. did it with its 4,000-ton cyclotron. The news caused a ...

Add Yahoo as a preferred source to see more of our stories on Google. Artist’s impression of the new particle, which contains two charm quarks and one down quark. Physicists just discovered a ...

A new particle has popped into existence at CERN’s Large Hadron Collider, a heavier proton-like particle that contains two charm quarks. Protons and neutrons are examples of a class of particles ...

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 ⁺ ...

Researchers at the Large Hadron Collider (LHC) have discovered a new particle, the Ξ cc ⁺, (“Xi cc plus”), a heavier cousin of the proton. The particle’s fleeting existence had made it invisible for ...

The new particle, named Xi-cc-plus, carries two heavy charm quarks and is about four times heavier than an ordinary proton. Reading time 3 minutes This summer, the world’s most powerful particle ...
