Abstract

We have studied the inclusive production of the hadrons π±, K±, p, p, Λ, Λ, ρ and ⋉ in the central region at the ISR s = 53 GeV, in both pp and pp collisions. Differences are observed only for K±, p, and p production. We then study also correlations between low-pT pp and pp pairs in the two types of collisions, separating the contribution from baryon pair production and from the incident particles (stopping protons). We observe a positive correlation between two stopping protons; between the production of two pairs, and between a stopping proton and a pair production, there are negative correlations.
