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

The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

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 ...

What is everything made of? It’s the fundamental question that lies at the heart of particle physics. Today, scientists are using gigantic, atom-smashing particle accelerators to probe deeper into 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 ...

The United States' military has announced it is seeking to create powerful subatomic particle beams that would enable personnel to "see" through walls tens of yards thick and even peer deep ...

They say you can never trust an atom because they make up everything. This week, we’re shrinking down and getting literally into the heart of the matter. We’ve covered the periodic table and all its ...

Snappily named Xi-cc-plus, Cern physicists spotted the particle in shower of debris that lit up Large Hadron Collider ...
