Russian scientists discovered a new elementary particle at the Large Hadron Collider

Russian engineers working at MIPT, MEPhI and FAN, who also work in the international CMS collaboration at The Large Hadron Collider at CERN, made a statement that they had discovered a new elementary particle.

The engineers discovered for the first time the orbital excitation (resonance) of a charmingly strange baryon.

The discovery of Russian scientists and the hard path to it

Russian scientists have been moving towards this discovery over the past two years. At first, it was far from obvious that scientists would be able to see anything from the new baryon. A lot of work has been done by engineers to maximize the experimental sensitivity.

For the analysis, the scientists used the data accumulated after proton-proton collisions, which were collected at the LHC in the period from 2016 to 2018.

For reference. LHC (Large Hadron Collider) – the largest experimental facility in the world (at the moment), on which acceleration of protons and heavy ions and their further collision with the subsequent analysis of their products collisions.

Over the entire period of operation of the installation, about 60 new elementary particles were discovered, including the famous Higgs boson.

And as a result of all this work, a new particle was discovered with sufficient statistical reliability. This was told by a senior researcher at the laboratory of high energies and associate professor at MIPT R. Chistov.

The new charmingly strange baryon discovered by Russian scientists (this is the real name of the particle) makes a significant contribution to the understanding of the strong nuclear interaction and thus will help various theoretical models to significantly better calculate the properties of hadrons (particles, their nuclei atoms).

In 2022, the LHC will be put back into operation after a deep reconstruction, after which the luminosity of the device will be increased. This means that scientists need to prepare for the discovery of new particles previously unknown to science, and, possibly, even expanding the horizons of existing theoretical physics.
