The review concerns mainly low p_t processes, including diffraction processes, and fragmentation of nuclei in nucleus-nucleus collisions. A short recollection is made of the first studies of high p_t processes. Conclusions and perspectives follow.12 pages, 15 EPS figuresHigh Energy Physics - Phenomenologytext
