Quark 2018 crashing3/30/2024 ![]() ![]() We now have evidence of a new state of matter where quarks and gluons are not confined. It is also an important step forward in the understanding of the early evolution of the universe. This result verifies an important prediction of the present theory of fundamental forces between quarks. Professor Luciano Maiani, CERN Director General, said "The combined data coming from the seven experiments on CERN's Heavy Ion programme have given a clear picture of a new state of matter. Our understanding of how the universe was created, which was previously unverified theory for any point in time before the formation of ordinary atomic nuclei, about three minutes after the Big Bang, has with these results now been experimentally tested back to a point only a few microseconds after the Big Bang. Theory predicts that this state must have existed at about 10 microseconds after the Big Bang, before the formation of matter as we know it today, but until now it had not been confirmed experimentally. At a special seminar on 10 February, spokespersons from the experiments on CERN 1's Heavy Ion programme presented compelling evidence for the existence of a new state of matter in which quarks, instead of being bound up into more complex particles such as protons and neutrons, are liberated to roam freely. ![]()
