Bose-Einstein study of position-momentum correlations of charged pions in hadronic $Z^{0}$ decays / OPAL Collaboration
A study of Bose-Einstein correlations in pairs of identically charged pions produced in e+e- annihilations at the Z0 peak has been performed for the first time assuming a non-static emitting source. The results are based on the high statistics data obtained with the OPAL detector at LEP. [...]

Rapidity-Alignment and $mrm{p}_T$ Compensation of Particle Pairs in Hadronic $Z^0$ Decays / DELPHI Collaboration
Observation is made of rapidity-alignment of \KK and \pp pairs which results from their asymmetric orientation in rapidity, with respect to the direction from primary quark to antiquark. The \KK and \pp data are consistent with predictions from the fragmentation string model. [...]

Transverse and Longitudinal Bose Einstein Correlations in hadronic $Z^0$ Decays / OPAL Collaboration
Bose-Einstein correlations in pairs of identical charged pions produced in asample of 4.3 million Z0 hadronic decays are studied as a function of the threecomponents of the momentum difference, transverse ("out" and "side") andlongitudinal with respect to the thrust direction of the event. A significantdifference between the transverse, r_t_side, and longitudinal, r_l, dimensionsis observed, indicating that the emitting source of identical pions, asobserved in the Longitudinally CoMoving System, has an elongated shape.

Bose-Einstein Correlations of $\pi^{0}$ Pairs from Hadronic $Z^{0}$ Decays / OPAL Collaboration
We observed Bose-Einstein correlation in pi0 pairs produced in Z0 decays using the data sample collected by the OPAL detector at LEP 1 from 1991 to 1995. Using a static Gaussian picture for the pion emitter source, we obtain the chaoticity parameter lambda = 0.55 +- 0.10 +- 0.10 and the source radius R = (0.59 +- 0.08 +- 0.05) fm. [...]

Bose-Einstein correlations of three charged pions in hadronic $Z^{0}$ decays / OPAL Collaboration
Bose-Einstein Correlations (BEC) of three identical charged pions were studied in 4 x 10^6 hadronic Z^0 decays recorded with the OPAL detector at LEP. The genuine three-pion correlations, corrected for the Coulomb effect, were separated from the known two-pion correlations by a new subtraction procedure. [...]

Genuine Correlations of Like-Sign Particles in Hadronic $Z^0$ Decays / OPAL Collaboration
Correlations among hadrons with the same electric charge produced in Z0 decays are studied using the high statistics data collected from 1991 through 1995 with the OPAL detector at LEP. Normalized factorial cumulants up to fourth order are used to measure genuine particle correlations as a function of the size of phase space domains in rapidity, azimuthal angle and transverse momentum.

Bose-Einstein Correlations of Neutral and Charged Pions in Hadronic Z Decays / L3 Collaboration
Bose-Einstein correlations of both neutral and like-sign charged pion pairs are measured in a sample of 2 million hadronic $\mathrm{Z}$ decays collected with the L3 detector at LEP. The analysis is performed in the four-momentum difference range $300 \mathrm{\ Me\kern -0.1em V} < Q < 2 \mathrm{\ Ge\kern -0.1em V}$ [...]

Bose-Einstein correlations in $K^{\pm}K^{\pm}$ pairs from $Z^{0}$ decays into two hadronic jets / OPAL Collaboration
Bose-Einstein correlations in pairs of charged kaons produced in a sample of 3.9 million hadronic Z0 decays have been measured with the OPAL experiment at LEP. Charged kaons were identified in the central tracking detector using their specific energy loss in the drift chamber gas. [...]

Directed and elliptic flow of charged pions and protons in Pb+Pb collisions at 40 and 158 AGeV / NA49 Collaboration
Directed and elliptic flow measurements for charged pions and protons are reported as a function of transverse momentum, rapidity, and centrality for 40 and 158 AGeV Pb + Pb collisions as recorded by the NA49 detector. Both the standard method of correlating particles with an event plane, and the cumulant method of studying multiparticle correlations are used. [...]

Measurement of Bose-Einstein Correlations in $e^{+}e^{-}\to W^{+}W^{-}$ Events at LEP / L3 Collaboration
Bose-Einstein correlations in W-pair production at LEP are investigated in a data sample of 629 pb$^{-1}$ collected by the L3 detector at $\sqrt{s}=$ 189--209\,GeV. Bose-Einstein correlations between pions within a W decay are observed and found to be in good agreement with those in light-quark Z decay. [...]
