Hjj production: Signals and CP measurements
Gunnar Klamke, Dieter Zeppenfeld
TL;DR
This paper discusses how Higgs boson production with two jets can be used to measure the CP properties of the Higgs-top Yukawa coupling through azimuthal angle correlations, distinguishing between electroweak and gluon fusion processes.
Contribution
It introduces a method to analyze azimuthal correlations of jets to directly measure the CP nature of the Higgs-top Yukawa coupling in gluon fusion production.
Findings
Azimuthal angle correlations reveal CP properties of the Higgs coupling.
Gluon fusion process provides a direct probe of the CP nature.
Method distinguishes between electroweak and gluon fusion contributions.
Abstract
Higgs boson production in association with two tagging jets will be mediated by electroweak vector boson fusion and by gluon fusion. For the gluon fusion process, analysis of the azimuthal angle correlations of the two jets provides for a direct measurement of the CP-nature of the Yukawa coupling which is responsible for the effective vertex.
