ZEUS was an experiment that was carried out at the electron-proton collider Hadron-Electron Ring Accelerator (HERA) at the German Electron Synchrotron (DESY) laboratory in Hamburg, Germany. This experiment ended in 2007. The ZEUS experiment studied the internal structure of the proton through measurements of deep inelastic scattering by colliding leptons (electrons or positrons) with protons in the interaction point of ZEUS.

The study of the production of baryons was conducted by NCPP using data from the ZEUS experiment.
