""This is the first new particle identified after the upgrades to the LHCb detector that were completed in 2023, and only the second time a baryon with two heavy quarks has been observed, the first having been observed by LHCb almost ten years ago.""
""The result will help theorists test models of quantum chromodynamics, the theory of the strong force that binds quarks into not only conventional baryons and mesons but also more exotic hadrons.""
The Large Hadron Collider has revealed a new particle called Xi-cc-plus, consisting of two charm quarks and one down quark. This discovery adds to the 80 new hadrons identified so far. The LHCb experiment, which focuses on heavy particles, made this observation possible after recent upgrades. The finding is significant as it allows theorists to test quantum chromodynamics, the theory explaining the strong force that binds quarks into baryons and mesons, including exotic particles.
