“…NA44 reported a result close to unity for Pb-Pb interactions, but a much lower result for S-Pb [8], both with no clear Q 3 dependence. WA98 also reported a result close to unity at Q 3 = 0 for Pb+Pb, and the Q 3 -dependence in their result is similar to what we see in central collisions [9]. Figure 4 shows the calculation of ε for STAR's measurements, and for those from WA98 and NA44.…”

“…Recently, the experimental investigation of the source coherence in the Pb-Pb collisions at √ s N N = 2.76 TeV at the Large Hadron Collider (LHC) was carried out by the ALICE collaboration [14]. A substantial degree of source coherence was measured [14], using a new three-pion interferometry technique with an improvement over the past efforts [15][16][17]. It is of interest to study the reasons of source coherence in heavy-ion collisions at the LHC energy.…”

We investigate the chaoticity parameter λ in two-pion interferometry in an expanding boson gas model. The degree of Bose-Einstein condensation of identical pions, density distributions, and Hanbury-Brown-Twiss (HBT) correlation functions are calculated for the expanding gas within the mean-field description with a harmonic oscillator potential. The results indicate that a sources with thousands of identical pions may exhibit a degree of Bose-Einstein condensation at the temperatures during the hadronic phase in relativistic heavy-ion collisions. This finite condensation may decrease the chaoticity parameter λ in the two-pion interferometry measurements at low pion pair momenta, but influence only slightly the λ value at high pion pair momentum.

“…Function r 3 is insensitive to resonance decay [15,[17][18][19]22], and is directly related to the condensation fraction for our space-symmetric EPG sources. Similarly, the normalized fourpion correlation function r 4 (p 1 , p 2 , p 3 , p 4 ) is defined by [23]…”

Recently, the ALICE collaboration analyzed the three-and four-pion Hanbury Brown-Twiss (HBT) correlations in Pb-Pb collisions at the Large Hadron Collider (LHC). The measured suppressions of three-and four-pion correlations may originate from a substantial coherence of the particle-emitting sources. In this work we investigate the normalized three-and four-pion HBT correlation functions for evolving pion gas (EPG) sources with Bose-Einstein condensation. We find that the intercepts of the normalized correlation functions at zero relative momentum are sensitive to source condensation and particle momentum. The normalized correlation functions in low average-momentum regions of three and four pions decrease with decreasing temperature and increasing particle number of the source, indicating a dependence of the normalized correlation functions on source condensation. However, this dependence becomes weak in an intermediate average-momentum region because particles with high momenta are likely emitted from excited states incoherently in the EPG model, even if the source has a considerable condensation fraction.For a wide momentum range, the normalized correlation functions for low source temperatures are enhanced at larger relative momenta because of a rapid increase of two-pion chaoticity parameter with increasing particle momentum. We hope the significant enhancement of the normalized fourpion correlation function at high relative momentum will be identified through future analyses of experimental data.

Three-Pion Interferometry Results from CentralPb+PbCollisions at158AGeV/c

Abstract: Three-particle correlations have been measured for identified pi(-) from central 158A GeV Pb+Pb collisions by the WA98 experiment at CERN. A substantial contribution of the genuine three-body correlation has been found as expected for a mainly chaotic and symmetric source.
