Recent results from the ZEUS Collaboration are presented on
the features of multiparticle correlations in photoproduction in ep
collisions at HERA. They are compared to correlations observed in deep inelastic ep scattering and to earlier results in heavy-ion
collisions at the LHC. No evidence for quark-gluon plasma formation is seen at HERA. Detailed correlaton coefficients are compared to various models, and it is concluded that multiparton collisions form an important part of the photoproduction process.
