Tests of the JETSET Bose-Einstein correlation model in the e+e-   annihilation process
  Studies of implementation of the simulation of the Bose-Einstein correlation effects in the JETSET particle generator are performed. Analysis of dependance of the one-dimensional correlation function parameters on the presumed boson source size reveals appearance of the effective new length scale, which limits applicability of the simple momentum-shifting mechanism, employed by JETSET to simulate the Bose-Einstein correlation. Two- and three-dimensional correlation functions are analysed as well and compared to the DELPHI data.
