Tomsk State University (TSU) reports that the results of experiments at the Large Hadron Collider (LHC) indicate the existence of an odderon – a hypothetical quasiparticle, which scientists have been searching for more than half a century.

] Recall that the BAC complex is an accelerator of charged particles in colliding beams, designed to disperse protons and heavy ions and to study the products of their collisions. The length of the main ring of the accelerator is about 27 km.

Traces of odderon were found in the framework of the TOTEM experiment. Its specificity is the measurement of protons scattering at very small angles. The specialists of TSU take part in the experiment.

Researchers study the processes that occur during the collision of protons, accelerated with the aid of the LHC to colossal energies. In central collisions, a special state of matter can be formed-quark-gluon plasma, and in peripheral states, bound states-objects called quasiparticles-that are not particles but which behave similarly can arise.

The hypothesis of the existence of odderon, theorists expressed in the 1970s. Odderon is the bound state of an odd number of gluons. In atomic nuclei, gluons hold protons and neutrons together, and also “glue” quarks in the protons and neutrons themselves “reports TSU.

Until now, quasiparticles consisting of only an even number of gluons have been formed. However, recent measurements have shown for the first time evidence of an exchange of an odd number of gluons. Now experts have to confirm or refute the results.
