Physicists observing data from the Large Hadron Collider beauty (LHCb) collaboration in Geneva have found three never-before-seen “exotic” particles, adding to a growing list of sub-atomic particles that scientists know to make up the universe.
The newly discovered particles – described at a seminar on Tuesday – include a previously unseen pentaquark and the first-ever pair of tetraquarks that includes a whole new type of tetraquark.
