Abstract

NA61/SHINE is a fixed target experiment at the CERN Super Proton Synchrotron. The main goals of the experiment are to discover the critical point of strongly interacting matter and to study the properties of the onset of deconfinement. In order to reach these goals, a study of hadron production properties is performed in nucleus-nucleus, proton-proton and proton-nucleus interactions as a function of collision energy and size of the colliding nuclei. In this talk, the new results on identified charged kaon production in the intermediate size system (Ar+Sc and Be+Be) collisions at SPS beam momentum range (13A-150A GeV/c) will be shown. Additionally, the new measurements of strange mesons (KS0), resonances (K0*(892), Xi(1530) 0 and Xi0(1530)) and baryons (Xi-(1321), Xi+(1321)) produced in p+p interactions are presented.
