Quark-mass effects for jet production in e^+ e^- collisions at the next-to-leading order: results and applications

TL;DR

This paper calculates next-to-leading order QCD corrections for heavy quark production in electron-positron collisions, incorporating mass effects, and explores how specific jet observables can be used to determine the bottom quark mass at the Z boson peak.

Contribution

It provides a detailed NLO QCD calculation including mass effects and demonstrates how to extract the bottom quark mass from jet observables at the Z peak.

Findings

NLO QCD corrections with mass effects are computed.

Jet observables can be used to determine m_b(m_Z).

Results are applicable to data analysis at the Z resonance.

Abstract

We present a detailed description of our calculation of next-to-leading order QCD corrections to heavy quark production in e^+ e^- collisions including mass effects. In particular, we study the observables $R_3^{b\ql}$ and $D_2^{b\ql}$ in the E, EM, JADE and DURHAM jet-clustering algorithms and show how one can use these observables to obtain $m_b(m_Z)$ from data at the $Z$ peak.
