An international team of scientists working in one of the experiments of the Large Hadron Collider (LHC), the most powerful particle accelerator to date has been successful in obtaining an exotic form of matter, the so-called primordial quark-gluon plasma. matter in this form existed only at the initial moment of creation of the Universe. And now it was obtained using a smaller number of collisions of smaller particles that previously thought impossible, even from a theoretical point of view. Traces of the quark-gluon plasma have been found at the site of the collision of high-energy protons with overclocked cores of atoms, ions of lead. These collisions were performed in the experimental area of ​​the sensor Compact Muon Solenoid (CMS), high sensitivity is possible to reveal traces of the tiny "droplets" superfluid, which is the quark-gluon plasma. "Previously it was thought that the energy-rich environment created by collisions of protons with lead nuclei will be too weak to ensure that it could be formed quark-gluon plasma" - says Kuan Wang (Quan Wang), a researcher at the University of Kansas, who worked with the team Scientists CERN, - "We have been studying these collisions in terms of detection of secondary collisions of lead ions, and the effects of these collisions. However, the results of the experiment showed us the clear signature traces of quark-gluon plasma." Kkvarkovo-gluon plasma is a very dense, very hot material, consisting only of quarks and gluons, which does not contain even a single nucleon, particles, which are then formed the nucleus of the atoms of all chemical elements. It was in this state all the matter in the Big Bang, and a short time later it. Then, once formed the Universe has expanded to a certain size, the plasma has cooled down, and lost the density of the quarks and gluons started to form the first elementary particles, which after some more time, began to coalesce into the nucleus of the lightest chemical elements - hydrogen and helium. It should be noted that this is not the first case in the history of science when the scientists managed to get a quark-gluon plasma. Earlier, a similar succeeded scientists from Brookhaven National Laboratory, which used accelerator Relativistic Heavy Ion Collider (RHIC). As part of the experiment PHENIX (Pioneering High energy Nuclear Interaction eXperiment) in the depths of RHIC collider collision produced nuclei of helium-3 ions of gold, with an excess of energy which is enough to form a "droplet" quark-gluon plasma. Such research will enable scientists to better understand all the processes taking place in the first microseconds after the Big Bang, and this, in turn, can make changes in the understanding of the "work" of the Universe to the present day. Currently, a group of scientists CERN, which includes scientists from the University of Kansas are still working on the analysis of existing scientific data and the new data collected using scientific instrument Zero Degree Calorimeter.
