摘要:Abstract(#br)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⋅GeV beam ...

摘要:Abstract(#br)The NA49 results on hadron production obtained in PbPb collisions at SPS energies from 20 to 158 A GeV are shown and discussed as evidence for the onset of deconfinement. The primary measures are the pion yield, the kaon-to-pion ratio and the slope parameter of trans...

摘要:Abstract(#br)The production of protons, anti-protons, neutrons, deuterons and tritons in minimum bias p+C interactions is studied using a sample of 385 734 inelastic events obtained with the NA49 detector at the CERN SPS at 158 GeV/c beam momentum. The data cover a phase spa...

摘要:Abstract(#br)With its large acceptance and particle identification coverage the NA49 experiment (Fig. 1) can study hadron production in a wide range of high energy reactions [1]. Originally aimed at examining central Pb+Pb collisions for signatures of quark-gluon plasma formation...

摘要:Abstract(#br)Data on φ -production obtained by the CERN NA49 experiment for central Pb+Pb collisions at 158 GeV/u are presented. Compared with pp interactions the φ -yield shows substantial strangeness enhancement: the φ /π ratio is found to increase by a factor of 2.6 ...

摘要:Abstract(#br)Recent results on hadron production in central nucleus-nucleus collisions obtained by the experiment NA35 at the CERN SPS are reviewed. The first preliminary results on central Pb+Pb collisions obtained by the NA49 experiment, the successor of NA35, are also discusse...

摘要:Abstract(#br)First results from the NA49 experiment with a 208 Pb beam on a Pb target at the CERN SPS with total energy of 33 TeV are presented. Data on transverse energy production, forward energy flow and rapidity density of negative hadrons are shown and discussed. The degree ...

摘要:Abstract(#br)Source imaging methodology is used to provide a three-dimensional two-pion source function for mid-rapidity pion pairs with p T < 70 MeV / c in central (0–7%) Pb + Pb collisions at s NN = 17.3 GeV . Prominent non-Gaussian tails are observed in the pion pair tran...
