About agreement of PYTHIA and the experimental results in $e^{+}{e}^{-}$ annihilation to hadrons

Abstract

The experimental charged particles multiplicity distributions in $e^{+}{e}^{-}$ annihilation to hadrons are compared with the distributions obtained by PYTHIA. The ratio ${\chi }^2$/degrees of freedom is calculated for 6 energies at $\sqrt{s}$ 14 -- 206.2 GeV. The necessity of more subtle tuning of PYTHIA at the energy of $Z^0$ peak is discussed.
