چکیده
We are presenting here the new formulae for Bose-Einstein correlations (BEC) which contain effects of final state interactions (FSI) of both strong (in s-wave) and electromagnetic origin. We demonstrate the importance of FSI in BEC by analysing data for e + e − annihilation and for heavy collisions. The inclusion of FSI results in the practical elimination (at least in e + e − data) of the so called degree of coherence parameter λ (which becomes equal unity) and the long range parameter γ (which is now equal zero).

We report on a systematic treatment of Coulomb corrections for 3-and n-particle (Bose-Einstein) correlations, leading to a removal of a 100 % systematic error from earlier Coulomb corrections of 5-particle Bose-Einstein correlations in heavy ion collisions. These results are generalized to include strong final state interactions and core-halo effects.

The studies of Fermi–Dirac correlations of ΛΛ and ¯ Λ ¯ Λ pairs in hadronic Z decays, Bose–Einstein correlations and colour reconnection in W-pairs decays performed by the ALEPH collaboration in e + e − annihilation at LEP are presented. The OPAL analysis of Bose–Einstein correlations in W-pair decays is also discussed.
