Scientists were able to measure the strength of the interaction of antiprotons
An international team of physicists for the first time to accurately measure the strength of the interaction of antiprotons - the particles of antimatter. During the experiments, the American RHIC collider researchers dispersed gold ions to near-light speed. Thus they were able to find out what the roots of the baryon asymmetry of the universe.
The study is published in the magazine Nature. The experiments were carried out at the relativistic heavy ion collider (RHIC), which is located at the Brookhaven National Laboratory in the US. The study involved an international team of physicists, including Russian. At RHIC collider face overclocked to near light speeds gold ions. As a result of these clashes in a very short time, the conditions in which there is a substance through the moments after the Big Bang.
As commonly understood today, at the birth of the universe particles and antiparticles should have to appear in equal amounts. Now, however, there is no antimatter in the universe. Scientists hope to find out what the cause of this asymmetry. In analyzing data from RHIC, they found traces of a pair of strong interaction of antiprotons.
The strong interaction - one of the four fundamental interactions in physics. It brings together the quarks, gluons and composed of these particles called hadrons. They hold atoms together into protons and neutrons and elementary particles - from the decay into quarks. It is believed that in the early stages of the Universe there was one strong and electroweak interactions, from which the inflationary stage (in the interval of exponential expansion) was the allocation of the strong interaction.
Physicists wondered what the reason for the absence of antimatter in the universe, and if she could lie in the fact that the nature of the strong interaction between its particles may be little, but differ on how to interact with each other, protons, neutrons, and other inhabitants of the microcosm of matter. It turned out that all options, including the strength of the interaction of antiprotons are identical. "They made a very difficult measurement," - says physicist William Gibbs from the State University of New Mexico.
All this, as explained by scientists, suggests that the roots of the baryon asymmetry of the universe - the predominance of matter over antimatter in the observable universe - to be found in some other place. Now physicists can begin a serious study of complex nuclei of atoms of antimatter - antideuterium, antitritium, antihelium-3 and 4 received the same RHIC.
