In the world of quantum mechanics and subatomic quantities to theoretical physicists, in most cases, are ahead of their own fellow practitioners, anticipating the certain provisions even before their experimental confirmation.
In the late 60-ies of the last century, scientists created an indirect confirmation of the existence of simple particles, conscious for the transfer of strong (nuclear) interaction. What does this mean? Remember that the core of any chemical component consists of protons and neutrons. But these core parts are not considered to be indivisible, they are based on the quarks that are bound together not by some fictitious invisible threads, and "glued" using a brand certain particles - gluons. Glue means "glue", hence the name data of elementary (i.e. indivisible into components) of particles.
Here we cannot but add that all ordinary particles are of 2 types: the bosons, responsible for the transfer of forces, and fermions, the fundamental matter actually. The traditional example of the first type of particles can be photons that carry the force of electromagnetic radiation.
The gluons can be considered as a more difficult form of photons. The latter, as we have said, are responsible for electromagnetic forces, and 1st play such a role in the strong (nuclear) interaction. But a fundamental difference lies in the fact that gluons, unlike photons, are triggered by their own forces. Because photons do not communicate with each other in the particles, and the gluons in the theory can unite.
Already in 1972, Nobel laureate Murray Gell-Mann (Murray Gell-Mann) and physicist Harald Fritsch (by Harald Fritzsch) provided that the gluons can communicate with each other, forming a so-called gluonic or global - particle consisting of pure force. In other words, the force that unifies the individual quarks, are ready themselves to join and even to exist in a space separate from its parent particle.
It soon became clear that the elusive particles are so unstable that you can find them solely at the footsteps of decay. But to do this in practice is rather difficult, as the scenario of this collapse are still not amenable to concrete calculation.
In the process of long searches at accelerators scientists a couple of times already reported the detection of potential contenders for the title globalaw. More than just this role came up 2 types of mesons - particles consisting of 1 quark and 1 antiquark opposite him, the merger of which is likely and ensures a great nuclear power that binds together the more solid particles.
Directly component parts of data scientists and could be detected in accelerators, considering them to be the remnants of the decay particles of force. But many skeptics believed that the signal attributed to globalam, could with equal probability to belong to the normal conglomerates of quarks and the latter now have obtained, in consequence of this no 1 from past cases was not considered convincing.
For a long time on a number of mathematical criteria for a favorite was the meson f0(1500). However, the other meson f0(1710) has a higher mass and better agree with models globalaw developed on computers. But physicists were alarmed by the precedent that when the decomposition is formed very a lot of heavy elementary particles known as strange quarks. According to the basic doctrine gluon interactions do not distinguish between heavy and light quarks. From this we can conclude that the decay of physics has undertaken to observe different particles.
And now here we are, in the end, got to the new research in this area. In his own work Dr. Anton Rebhan (Anton Rebhan) and graduate student Frederic Brunner (Frederic Br
