Hadron multiplicity in e+e- events induced by top quark pairs at the ILC energy

Abstract

The average charged hadron multiplicity in the $e^{+}{e}^{-}$ events with the primary $t\bar{t}$-pair at the collision energy 500 GeV, as well as the average multiplicity of charged hadrons from the top quark are calculated in QCD to be $86.7\pm 1.11$ and $41.0\pm 0.54$, respectively.
