Pion-pion correlations in Au+Au collisions at AGS energy
Pion-pion correlation functions have been measured in Au+Au collisions at 10.8 GeV/c per nucleon by the E877 collaboration. The width of the peak in the correlation function for identical pions, which is related to the source size, shows a dependence on pion momenta and on the orientation of the reaction plane
Two-pion correlations in Au+Au collisions at 10.8 GeV/c per nucleon
Two-particle correlation functions for positive and negative pions have been
measured in Au+Au collisions at 10.8~GeV/c per nucleon. The data were analyzed
using one- and three-dimensional correlation functions. From the results of the
three-dimensional fit the phase space density of pions was calculated. It is
consistent with local thermal equilibrium.Comment: 5 pages RevTeX (including 3 Figures
Decoding the phase structure of QCD via particle production at high energy
Recent studies based on non-perturbative lattice Monte-Carlo solutions of
Quantum Chromodynamics, the theory of strong interactions, demonstrated that at
high temperature there is a phase change from confined hadronic matter to a
deconfined quark-gluon plasma where quarks and gluons can travel distances
largely exceeding the size of hadrons. The phase structure of such strongly
interacting matter can be decoded via analysis of particle abundances in high
energy nuclear collisions within the framework of the statistical hadronization
approach. The results imply quark-hadron duality at and experimental
delineation of the location of the phase boundary of strongly interacting
matter.Comment: 15 pages, 8 figures; v2: final version accepted for publication in
