Abstract
From a sample of 2.36 million minimum bias events produced in pp collisions at s=630 GeV in the UA1 experiment and from other published data at the CERN SppS collider we have estimated the relative production of π±, π0, K±, KS0, Λ, Λ, p and p. We obtain a meson over baryon ratio MB = 6.4 ± 1.1. From the KS0π± ratio we measure the strangeness suppression factor λ = 0.29 ± 0.02 ± 0.01 which, combining with other available data provides a new world average of 0.29 ± 0.015. Both the KS0π± ratio and the strangeness suppression factor λ as a function of s are investigated, and an extrapolation to the LHC energy is performed.
