      We would like to defer a more detailed summary of our (pre 31st march) finalised results until Thursday 27th. The current status is:

      • Working on our paper draft which includes a discussion of our simulation framework (using Madgraph with SMEFTSim for the interference samples), the CP-odd operators we are considering, and the limit-setting calculation. If this is not submitted before 31st March we will upload the draft as an FCC note so there is a reference.
      • Results will include ZH production at e+e- (including consideration of polarisation), and pp colliders (HL-LHC and FCC-hh),  H->4l in pp collisions (HL-LHC and FCC-hh), and VBF H->tautau in pp collisions (HL-LHC and FCC-hh) and we plan to present some distributions showing SM and SM+interference for CP odd observables (including NN defined observables in some cases) and expected limits on Wilson coefficients.
      • Anticipated message relevant for FCC-hh ESPPU submission along the lines of "FCC-hh can provide order of magnitude improvements in constraints on CPV HVV couplings when considering interference effects in CP odd observables, that can be further enhanced through the use of ML techniques."
