Researchers confirm existence of rare ‘exotic’ particle, find evidence of 3 others. Physicists have made science history by confirming the existence of a rare 4-quark particle and discovering evidence of 3 other “exotic” siblings. Their findings are based on data from the Large Hadron Collider (LHC) particle accelerator, CERN, Geneva, Switzerland. The tetraquark candidate is X(4140). The other 3 have higher masses, called X(4274), X(4500) and X(4700).
