Study of Λ-production in target fragmentation region from pp interactions at 360 GeV/c in the triple regge framework

A study of Λ production has been made in the target fragmentation region frompp interactions at 360 GeV/c. The triple Regge analysis of the double differential distribution d 2 N/d(M 2/s)dt led to an estimate of the kaon trajectory intercept as ≈-0.6. Comparison of the double and single inclusive distributions supports the idea of Pomeron factorization. The charged multiplicities and moments from virtual 'K +'p interactions have been studied as a function of M, the c.m. energy of the virtual 'K +'p system. The results agree reasonably well with the on shell K + p data

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.jinfo:eu-repo/semantics/publishe
