Scientists at the Large Hadron Collider have announced the discovery of a new particle called the pentaquark.
- "The pentaquark is not just any new particle… It represents a way to aggregate quarks, namely the fundamental constituents of ordinary protons and neutrons, in a pattern that has never been observed before in over fifty years of experimental searches.
"Studying its properties may allow us to understand better how ordinary matter, the protons and neutrons from which we're all made, is constituted."
