Higgs decays to Z boson pairs may be exploited to determine spin and parity of the Higgs boson, a method complementary to spin-parity measurements in Higgs-strahlung. For a Higgs mass above the on-shell ZZ decay threshold, a model-independent analysis can be performed, but only by making use of additional angular correlation effects in gluon-gluon fusion at the LHC and gamma-gamma fusion at linear colliders. In the intermediate mass range, in which the Higgs boson decays into pairs of real and virtual Z bosons, threshold effects and angular correlations, parallel to Higgs-strahlung, may be adopted to determine spin and parity, though high event rates will be required for the analysis in practice.

  1. AI-Driven Discovery of Information-Efficient Collider Observables for Interference Measurements

    hep-ph 2026-05 unverdicted novelty 6.0 of 10

    AI-driven symbolic evolution discovers interpretable event-level observables that retain substantially more local Fisher information than angular baselines for CP-sensitive HZ interference in two collider channels.

  2. Probing P and CP Violations on the Cosmological Collider

    hep-ph 2019-09 conditional novelty 6.0 of 10

    A rolling axion-like coupling to a massive gauge boson generates a CP-odd imaginary trispectrum of primordial fluctuations, while local four-scalar EFT operators in exact de Sitter space produce no observable signal.

  3. Future Collider Perspectives on Higgs CP Violation

    hep-ph 2025-11 conditional novelty 5.0 of 10

    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.
