High energy Pb + Pb collisions viewed by pion interferometry

Two-pion correlations from Pb+Pb collisions at 158 GeV/$c$ per nucleon are measured by the NA44 experiment at CERN. Multidimensional fits characterize the emission volume, which is found to be larger than in S-induced collisions. Comparison with the RQMD model is used to relate the fit parameters to...

Descripción
Sumario:Two-pion correlations from Pb+Pb collisions at 158 GeV/$c$ per nucleon are measured by the NA44 experiment at CERN. Multidimensional fits characterize the emission volume, which is found to be larger than in S-induced collisions. Comparison with the RQMD model is used to relate the fit parameters to the actual emission volume.
