Abstract
We have analysed a sample of 2.36 million minimum bias events produced in p p collisions at s =630 GeV in the UA1 experiment at the CERN Sp pS collider. We have studied the production of K S 0, Λ and Λ particles with transverse momenta ( p t ) up to 7 GeV/c and K ± up to 2 GeV/c. The kaon data are compared with a recent QCD prediction and are found to be in good agreement. The < p t > for K S 0, Λ and Λ is seen to increase as a function of the charged particle multiplicity and is compared with charged particle production.
