   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pad chambers; PHENIX; WA98; phi-meson; tracking; single particle spectra; heavy-ion collisions; inverse slope parameters; particle production; RHIC; charged particle multiplicity; pad readout; SPS; Physics; Fysik; Atomic and molecular physics; Atom- och molekylärfysik; Fysicumarkivet A:2001:Nilsson;

   Sammanfattning : This thesis is about high energy heavy ion physics. Two major experiments, the WA98 at CERN and the PHENIX at Brookhaven National Laboratory, are described. Results from data analysis from both experiments are presented. The WA98 chapter presents particle identification methods and phi-meson measurements. LÄS MER

3. 2. Tracking Chambers with Two-Dimensional Readout used for Extraction of Particle Production Ratios in High Multiplicity Pb+Pb Collisions at 158 A GeV
