Predictions of a thermodynamical model of hadron production for multiplicity
distributions in e+e− annihilations at LEP and PEP-PETRA centre of mass
energies are shown. The production process is described as a two-step process
in which primary hadrons emitted from the thermal source decay into final
observable particles. The final charged tracks multiplicity distributions turn
out to be of Negative Binomial type and are in quite good agreement with
experimental observations. The average number of clans calculated from fitted
Negative Binomial coincides with the average number of primary hadrons
predicted by the thermodynamical model, suggesting that clans should be
identified with primary hadrons.Comment: 15 pages, LaTeX file, uses epsfig.sty and cite.sty, 3 figures added
