Intermittency and correlations in hadronic $Z^0$ decays / OPAL Collaboration
A multidimensional study of local multiplicity fluctuations and multiparticle correlations of hadrons produced in Z decays is performed. The study is based on the data sample of more than 4 million events recorded with the OPAL detector at LEP. [...]

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.

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. [...]

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. [...]

Multiplicity distributions of gluon and quark jets and tests of QCD analytic predictions / OPAL Collaboration
Gluon jets are identified in e+e- hadronic annihilation events by tagging two quark jets in the same hemisphere of an event. The gluon jet is defined inclusively as all the particles in the opposite hemisphere. [...]

Study of Tau-pair Production in Photon-Photon Collisions at LEP and Limits on the Anomalous Electromagnetic Moments of the Tau Lepton / DELPHI Collaboration
Tau-pair production in the process e+e- -> e+e-tau+tau- was studied using data collected by the DELPHI experiment at LEP2 during the years 1997 - 2000. The corresponding integrated luminosity is 650 pb^{-1}. [...]

Bose-Einstein correlations in $W^{+}W^{-}$ events at LEP2 / DELPHI Collaboration
Bose-Einstein correlations (BEC) between final state particles in the reaction e+e- -> W+W- -> q_1 anti-q_2 q_3 anti-q_4 have been studied. Data corresponding to a total integrated luminosity of 550 pb^{-1}, recorded by the DELPHI detector at centre-of-mass energies ranging from 189 to 209 GeV, were analysed. [...]

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. [...]
