TL;DR

This paper calculates the average charged hadron multiplicity in electron-positron collisions producing top quark pairs at 500 GeV, providing specific numerical predictions within QCD.

Contribution

It offers the first detailed QCD-based predictions for hadron multiplicities in top quark pair events at the ILC energy.

Findings

Average charged hadron multiplicity in e+e- with top pairs: 86.7 ± 1.11

Charged hadrons from top quark: 41.0 ± 0.54

Quantitative predictions for future collider experiments

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.
