Abstrakt: Energy, charge and strangeness flow inK+p interactions at 32 and 70 GeV/c, and p+p interactions at 32 GeV/c are studied in terms of the angular variable ?=|x|/pT. The data ondQ/d? anddE/d? show only a weak indication of scale breaking between 32 and 70 GeV/c. For inclusive “non-diffractive”, inclusive “diffractive” and exclusive “non-diffractive” jets, the fraction of charge in any angular region ?O away from the central region is found to be proportional to the energy fraction in the same interval. The data ondQ/dE versus ? are compatible with some versions of dual-sheet models and agree also with the LUND Monte-Carlo model. The data are also compared with $$v(\bar v)p$$ interactions in BEBC. In exclusive channels the average ratiodQ/dS=0.78±0.04 is consistent, in the framework of fragmentation models, with a larger probability for the fragmentation of the $$\bar s$$ -valence quark than theu-valence quark in theK+-meson.
