| Abstract: | A model,which treats three initial parlous as two color singlets and then both of them fragment independently into hadrons, is employed to study the angular dependence of charged multiplicity distribution in e+ e- annihilation into three-jet events at LEP energy region. The calculated results show a distinguished dependence of charged multiplicity to topology structure of events, and also agree well with experiment data from ALEPH collaboration. |
