The Large Hadron Collider beauty (LHCb) experiment — which is investigating the slight differences between matter and antimatter by studying a type of particle called the “beauty quark”, or “b quark” — has observed three never-before-seen particles, CERN announced on July 5.

The three “exotic” additions — a new kind of “pentaquark” and the first-ever pair of “tetraquarks” — to the growing list of new hadrons found at the LHC will help physicists better understand how quarks bind together into these composite particles, CERN said in a release.

CERN — Conseil Européen pour la Recherche Nucléaire — is the original name of the European Organisation for Nuclear Research

which runs the particle accelerator complex that houses the LHC, the world’s largest and most complex collider.

smashing together protons at almost the speed of light, which could throw up “new” physics beyond the Standard Model.
