Charged pion production in 32GeV/c K+p interactions

Final data on topological cross sections are presented. Inclusive single particle distributions for the reactions K+p→ π±X at 32 GeV/c are discussed and compared with data at lower energies. Early scaling in the fragmentation regions is confirmed, while cross sections in th central region continue to rise with energy even faster than in pp interactions. The x-and pT-dependence of the π+/π- ratio in K+p interactions is discussed and a comparison of reactions K+p→ π±X and K-p→ π±X at 32 GeV/c is made in the context of constituent models. We also present transverse momentum distributions, show prominent seagull effects and study how they are influenced by resonance production. © 1980 Springer-Verlag.SCOPUS: ar.j
