Query: Hadronic final state interactions at ALEPH and OPAL   The studies of Fermi-Dirac correlations of $\Lambda\Lambda$ and
$\bar{\Lambda}\bar{\Lambda}$ pairs in hadronic $\mathrm{Z}$ decays,
Bose-Einstein correlations and colour reconnection in $\mathrm{W}$-pairs decays
performed by the ALEPH collaboration in $\mathrm{e^+e^-}$ annihilation at LEP
are presented. The OPAL analysis of Bose-Einstein correlations in
$\mathrm{W}$-pair decays is also discussed.
