A group of Uzbek physicists under the scientific leadership of Academician Bekzod Yuldashev for the first time in the world received experimental confirmation of the existence of a new elementary particle.

According to the Academy of Sciences of Uzbekistan, when analyzing the interactions of carbon nuclei at primary energy of 3.4 GeV per nucleon with carbon nuclei, a new resonant particle was discovered, which is an eight-quark system consisting of two protons and a pi meson.

The mass of the detected short-lived particle is 2118 ± 1 MeV/s2, and in terms of the time of strong interactions, it is a relatively long-lived particle (the width of the new resonance is no more than 4 MeV/s2).

The experimental excess of the observed resonance structure over the background distribution is 122± 20 events, or 4.5 standard deviations (sigma).

The obtained data on the new resonant particle are published by the authors in the International Journal of Modern Physics E (Nuclear Physics) of the international publishing house World Scientific, indexed in the Web of Science and Scopus databases.

Currently, the authors of the article are working with other experimental data on the interaction with nuclei in which the specified particle can be observed.
