DESCRIPTION:Speakers: Elena Kokoulina (JINR)\nMultiparticle production sti
 ll attracts our attention. Simulation by using Monte Carlo event generator
 s is performed before planning any experiment. But it often overestimates 
 (or underestimates) experimental data.\nOf all multiparticle processes\, $
 e^+e^-$ annihilation is the theoretically cleanest\, proceeding via an int
 ermediate virtual photon or $Z^0$-boson followed by $q\\bar q$ pair creati
 on. QCD describes well the development of\n$q\\bar q$ cascade as marcovian
  branching process.\nThe transformation of quarks and gluons into observab
 le hadrons occurs at hadronization\, to which perturbation theory is no lo
 nger applicable. The choice of a scheme for it is based on experimental da
 ta. Convolution of cascade and hadronization allowed us to describe the mu
 ltiplicity. This model is called the gluon dominance model.\nSeveral decad
 es have passed since a series of e+e− annihilation experiments were\ncar
 ried out. The hadron and heavy ion research revealed many new results.\nTh
 at is why it appeared necessary to analyze multiplicity n e+e−-annihilat
 ion again\n\nhttps://indico.particle.mephi.ru/event/626/contributions/6145
