Production of strange resonances in C+C and Pb+Pb collisions at 158 AGeV

摘要

The experiment NA49 at the CERN-SPS measures phi (K) over bar*(892)degrees and (1520) through their hadronic decay channels. For the phi meson we present the evolution of transverse spectra and total yields from p+p over C+C to Pb+Pb at various centralities. The (K) over bar*(892)degrees yield is given for different centralities in Pb+Pb. The yield of Lambda(1520) in central Pb+Pb is compared to that obtained in p+p and p+Pb collisions at the same beam energy. [References: 3]
