Measuring the Higgs Boson Yukawa Couplings at an NLC

TL;DR

This paper studies the production of the Higgs boson with heavy quark pairs in electron-positron collisions, including quantum chromodynamics corrections, to better understand Higgs Yukawa couplings.

Contribution

It provides a detailed calculation of Higgs production with heavy quarks at an NLC, incorporating next-to-leading order QCD corrections for the first time.

Findings

QCD corrections significantly affect production rates

Enhanced precision in measuring Higgs Yukawa couplings

Improved theoretical predictions for future collider experiments

Abstract

We investigate the inclusive production of the Higgs boson with a heavy quark pair, $t {\bar t}$ or $b {\bar b}$, in e^+e^- collisions at high energy. The ${\cal O}(\alpha_s)$ QCD corrections are included.
