abstract
We demonstrate that certain weighted moments of $t\anti t \h$ production can provide a determination of the CP nature of a light neutral Higgs boson produced and detected in this mode at the CERN LHC.

$t \bar{t}$ production as a window to invisible new physics
Phenomenological LHC study finds sensitivity to light spin-1 DM mediators in ttbar events and discrimination power from CP-sensitive angular observables in dileptonic final states.

Measurement of the Higgs boson production in association with top quarks in multilepton final states in $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector
ATLAS measures the ttH cross-section at 0.63+0.20−0.19 of the Standard Model prediction (3.3σ observed, 5.3σ expected) and excludes top-Higgs CP-mixing angles |α|>62° at 68% confidence.

Sensitivity to $\mathcal{CP}$-violating effective couplings in the top-Higgs sector
Combining ttbar H and single-top H production at the LHC can separate the real and imaginary parts of a CP-violating top Yukawa coupling, with projected HL-LHC constraints about twice as strong as current ATLAS bounds.

The Role of the $t{\bar t}h$ Rest Frame in Direct Top-Quark Yukawa Coupling Measurements
Evaluating the b2 and b4 angular observables in the ttbar h rest frame, instead of the lab frame, reduces by about 250 inverse femtobarns the integrated luminosity needed to exclude a pure CP-odd top-quark Yukawa coupling.
