Bose-Einstein Correlation of High Energy Heavy Ion Collisions at CERN SPS
Abstract
An experimental study was conducted at CERN, the European Organization for Nuclear Research, using the focussing spectrometer of the Experiment NA44 collaboration. Single particle spectra and two or three particle correlations for pi^+/-, K ^+/- and p^+/- were studied, for collisions of 450 Acdot GeV proton and 200 AcdotGeV S^{32} incident on Pb ^{208}, Be^9 and S^{32} targets. Results of pi^+pi^+ correlations from S + Pb collisions, pi ^-pi^- correlations from S + Pb collisions and pi^+pi^+ correlations from p + Pb collisions are presented in this thesis. Data have been fitted to a few different parameterizations. The two-pion correlation results are then compared with the kaon correlation results and other experiments' two-pion correlation results. The pion source radii are found to be larger than the kaon source radii and the pion correlation results are consistent with the results from other experiments. There is also very good agreement between our data and the Monte Carlo simulation results with RQMD.
