Abstract
The Higgs–gluon interaction is crucial for LHC phenomenology. To improve the constraints on the CP structure of this coupling, we investigate Higgs production with two jets using machine learning. In particular, we exploit the CP sensitivity of the so far neglected phase space region that differs from the typical vector boson fusion-like kinematics. Our results indicate that further improvements in the current experimental limits could be achievable using our techniques. We also discuss the most relevant observables and how CP violation in the Higgs–gluon interaction can be disentangled from CP violation in the interaction between the Higgs boson and massive vector bosons. Assuming the absence of CP-violating Higgs interactions with coloured beyond-the-Standard-Model states, our projected limits on a CP-violating top-Yukawa coupling are competitive with more direct probes like top-associated Higgs production and limits from a global fit.
Author comments upon resubmission
we thank you for the constructive feedback. We have implemented the suggestions and hope that our article is now suitable for publication.
Sincerely,

List of changes
- In the abstract, Section 5.3 and the conclusion, we weakened the statements about "significant improvements in experimental measurements" and emphasized that there are not just systematic uncertainties missing in our study.
- We modified footnote 3 according to the suggestion.
