Associated Particle Distributions in Jets Produced in Heavy-Ion Collisions

Abstract

We study the pion distributions in jets produced in heavy-ion collisions in association with trigger particles restricted to definite momentum ranges. We determine the centrality dependence of the associated particle distributions for both d+Au and Au+Au collisions in the recombination model. The central-to-peripheral ratios show significant dependence on centrality for Au+Au collisions, but negligible dependence for d+Au collisions. The results are in agreement with the qualitative features of the data.
