## Abstract

We evaluate the multiplicity of hadrons in the $e^+e^-$-annihilation at a given thrust $T$ in the modified leading-log approximation, including $O(\\sqrt{\\alpha\_s})$ corrections. The calculation is done at a large value of $\\tau =1-T$ by the use of the factorisation which takes place in the one-particle-inclusive cross section at a given $\\tau$. At a small $\\tau$, a different type of factorisation takes place, which also enable us to evaluate the multiplicity. Two approaches are compared numerically. Measuring this quantity near $\\tau =1/3$, we can determine the multiplicity ratio between a gluon-jet and a quark-jet.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
