Search for deconfinement in NA49 at the CERN SPS

[摘要] Experiment NA49 at the CERN SPS uses a large acceptance detector for a systematic study of particle yields and correlations in nucleus–nucleus, nucleon–nucleus and nucleon–nucleon collisions. Preliminary results for Pb + Pb collisions at 40, 80 and 158 A$cdot$GeV beam energy are shown and compared to measurements at lower and higher energies.
