Title: Study of jet production in nucleus-nucleus collisions at RHIC Author: Mgr. Zuzana Barnovská Department: Institute of Particle and Nuclear Physics Supervisor: RNDr. Jana Bielčíková, Ph.D., Nuclear Physics Institute of the ASCR Abstract: The goal of this thesis is to study strange particles (Λ, ¯Λ a K0 S) in jets at the energy of √ sNN = 200 GeV in d+Au and Au+Au collisions measured by the STAR experiment at RHIC in 2007 and 2008. After the application of geometrical and topological limits, jets were reconstructed with the kT and anti- kT jet algorithms and special selection criteria for strange particles were applied. Ratios of the production of strange baryons and mesons in jets were calculated and compared to previous results of inclusive V0 particle production measured by the STAR experiment. Study of centrality dependence of these ratios was performed and compared to values in d+Au collisions. Keywords: jets, d+Au collisions, Au+Au collisions, STAR, RHIC 1
