Improving the sensitivity to CP-violation in the Higgs sector is one of the pillars of the precision Higgs programme at the Large Hadron Collider. We present a simple method that allows CP-sensitive observables to be directly constructed from the output of neural networks. We show that these observables have improved sensitivity to CP-violating effects in the production and decay of the Higgs boson, when compared to the use of traditional angular observables alone. The kinematic correlations identified by the neural networks can be used to design new analyses based on angular observables, with a similar improvement in sensitivity.

  1. Future Collider Perspectives on Higgs CP Violation

    hep-ph 2025-11 conditional novelty 5.0

    Simulated future-collider studies project that FCC-ee and FCC-hh could constrain CP-violating Higgs EFT couplings 10-100 times more tightly than the HL-LHC, with the proton-proton machine strongest overall.
