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

Scientists have used CERN's Large Hadron Collider (LHC) to uncover what they say is an entirely new type of particle, dubbed ...

The new baryon “Xi-cc-plus” decays into other particles almost instantly, but its existence could paint a clearer picture on ...

The Large Hadron Collider has discovered a new particle, the 80th identified so far by the world's most powerful particle ...

Physicists working on the LHCb experiment at CERN’s Large Hadron Collider have discovered a new subatomic particle called the ...

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 ...

After years of failed searches, CERN has finally caught a needle in a subatomic haystack: a heavy relative of the proton ...

Researchers at the Large Hadron Collider (LHC) have discovered a new particle, the Ξ cc ⁺, (“Xi cc plus”), a heavier cousin ...

The proton is stretchier than we thought, according to new measurements. But physicists are divided on whether this anomaly will persist in future measurements or if our fundamental understanding of ...

A new measurement of the strong nuclear force, which binds protons and neutrons together, confirms previous hints of an uncomfortable truth: We still don’t have a solid theoretical grasp of even the ...

Protons might be stretchier than they should be. The subatomic particles are built of smaller particles called quarks, which are bound together by a powerful interaction known as the strong force. New ...

In a paper in Nature, the ALICE Collaboration 1 reports that data from high-energy collisions between protons can be used to investigate the little-understood nuclear forces between protons and ...
