KNO scaling in processes of electron-positron annihilation to hadrons

Abstract

The charged particles multiplicity distribution in the KNO form is discussed in processes of $e^{+}{e}^{-}$ annihilation at energies $\sqrt{s}$ 14 -- 206.2 GeV. The experimental data are compared to data, obtained with Monte Carlo simulation in PYTHIA in the Lund quark string model. It is shown, that both experimental and simulated data are described by the same distribution function in the KNO form. It is shown, that the KNO scaling is consequence of quark string hadronization dynamics in the Lund string model.
