Hadronic Final States in Photoproduction and DIS at HERA

摘要

Recent results from the HI and ZEUS experiments on the properties of the hadronic final states measured in high energy ep collisions at the HERA collider are preaeni ed. The phenomena observed in the interactions of virtual and almost real photons with protons are discussed in the framework of models based on perturbative QCD and the soft physics phenomenology.
