There’s a new exotic subatomic particle on the atom smasher. Physicists working with CERN’s Large Hadron Collider beauty (LHCb) collaboration have found a new form of the elusive four-quark particle called a tetraquark that they have never seen before.
The newly identified particle is made up of four quarks of the same flavour and is likely, scientists say, to be the first of a previously undiscovered class of particles.
The paper describing it has been uploaded to arXiv, and is yet to be peer-reviewed, but joins a growing body of evidence supporting the existence of exotic particles.
