On enhancement of Λ0 production in the proton-nucleus collisions and multiproduction models

Abstract

Production of Λ0 in the particlenucleus interactions is shown to be a particularily clean signature of reabsorption of the produced particles inside a nucleus. We find a significant enhancement of a relative fraction ofp A collisions with two and three wounded constituent quarks of the projectile proton in the Λ0-containing events and predict resulting enhancement of the central rapidity density and mean multiplicity of charged particles and grey tracks in the Λ0 and Λ0Λ0-containingp Xe andp Ar collisions, studied by the NA5 collaboration. We predict multiplicities in the minimal bias and Λ0-containing deep-inelastic μXe collisions under study by E665 at FNAL.
