Cern, here is the Xi particle

Thanks to her, scientists will have the opportunity to study the "glue" that holds matter together - The discovery took place through the largest accelerator in the world, the Large Hadron Collider (LHC).

Discovered at Cern, the European Organization for Nuclear Research as well as the largest particle physics laboratory in the world, the Xi particle. Thanks to her, scientists will have the opportunity to study the "glue" that holds matter together.

The discovery was announced during the conference of the European Physical Society underway in Venice and is being published in the journal Physical Review Letters and took place through the largest accelerator in the world, the Large Hadron Collider (LHC), in particular by one of its four detectors: LHCb, coordinated by the Italian Giovanni Passaleva of the National Institute of Nuclear Physics.

"It is the first time that such a particle has been observed: a baryon with two heavy quarks", explained Donatella Lucchesi, researcher at the National Institute of Nuclear Physics (Infn) and the University of Padua and member of the Lhcb collaboration. “Observing such a particle – she continued – was possible thanks to the huge amount of data that the LHC accelerator is producing. This makes it possible to achieve a difficult goal, such as being able to reproduce matter in all its possible states".

“In contrast to the other particles known so far, in which the three quarks perform an elaborate dance around each other, we expect the baryon with two heavy quarks to act like a planetary system, where the two heavy quarks play the role of stars orbiting each other, while the lightest quark orbits this binary system,” added Guy Wilkinson, former coordinator of the collaboration.
