Large Hadron Collider: Scientists at CERN observe three “exotic” particles for first time

Scientists at CERN say they have observed a new kind of "pentaquark" and the first-ever pair of "tetraquarks", adding three members to the list of new hadrons found at the LHC.

Scientists working with the Large Hadron Collider (LHC) have discovered three subatomic particles never seen before as they work to unlock the building blocks of the universe, the European nuclear research centre CERN said on Tuesday.

The 27 kilometre-long (16.8 mile) LHC at CERN is the machine that found the Higgs boson particle, which along with its linked energy field is thought to be vital to the formation of the universe after the Big Bang 13.7 billion years ago.

Now scientists at CERN say they have observed a new kind of “pentaquark” and the first-ever pair of “tetraquarks”, adding three members to the list of new hadrons found at the LHC.
