“…Figure 22 shows a comparison between HRM (points) and the trends of NA49 central 158 GeV/nucleon Pb+Pb experimental results 33 (dashed lines with same meaning as in Figure 21) for the k T dependence of the pion source parameters. Figure 23 compares an overview of HBT-extracted pion and kaon source parameters measured in the NA44 experiment 11,34,35,36 with those calculated with the HRM. Although there are some minor disagreements, the HRM is seen overall to qualitatively describe the trends of the data for both experiments.…”

“…As parameters that describe the size and shape of the particle emitting source, they fluctuate from event to event. Experimental data so far [2][3][4][5][6][7] determine only the average source radii characterizing a large ensemble of events [8]. Elsewhere [9] we discuss new ideas of how to complement such measurements of the ensemble-averaged HBT radii by a determination of their variances, i.e., the width parameters characterizing their event-by-event fluctuations.…”

Recent work has shown that a temperature dependence of the shear viscosity to entropy ratio, η/s, influences the collective flow pattern in heavy-ion collisions in characteristic ways that can be measured by studying hadron transverse momentum spectra and their anisotropies. Here we point out that it also affects the pair momentum dependence of the Hanbury-Brown-Twiss (HBT) radii (the source size parameters extracted from two-particle intensity interferometry) and the variance of their event-by-event fluctuations. This observation establishes interferometric signatures as useful observables to complement the constraining power of single-particle spectra on the temperature dependence of η/s.

“…Three collaborations measured and published data on Bose-Einstein correlations for 158 AGeV/c Pb+Pb collisions at the CERN SPS: WA98 [ 15], NA44 [ 16] and NA49 [ 11]. Due to their small acceptance, NA44 can only determine particle correlations in two transverse momentum bins which moreover correspond to slightly different rapidities.…”
