Analysis of the Coherence of Pion Emitting SourceThrough Multipion Correlations

  • The multiparticle correlations of pious eastted from sources with different degrees of coherence are simulated by Monte Carlo method. The sensitivity of the dependence of the multipion correlations in subevents with different multiplicities on the degree of coherence of the pion-emitting source is investigated. The degrees of coherence of the sources for central collisions of 2.1A GeV Ne+Pb and 1.2A GeV Ar+KCl at the Bevalac streamer chamber are analyzed. The results are compared with previous two-pion interferometry results.

Abstract: The multiparticle correlations of pious eastted from sources with different degrees of coherence are simulated by Monte Carlo method. The sensitivity of the dependence of the multipion correlations in subevents with different multiplicities on the degree of coherence of the pion-emitting source is investigated. The degrees of coherence of the sources for central collisions of 2.1A GeV Ne+Pb and 1.2A GeV Ar+KCl at the Bevalac streamer chamber are analyzed. The results are compared with previous two-pion interferometry results.
