Query: Measuring CP violation in Two-Higgs-Doublet models in light of the LHC
  Higgs data   In Two-Higgs-Doublet models, the conditions for CP violation can be expressed
in terms of invariants under U(2) rotations among the two SU(2) Higgs doublet
fields. In order to design a strategy for measuring the invariants we express
them in terms of observables, i.e., masses and couplings of scalar bosons. We
find amplitudes directly sensitive to the invariants. Observation of the
Standard-Model-like Higgs boson at the LHC severely constrains the models. In
particular, in the model with Z_2 symmetry imposed on dimension-4 terms (in
order to eliminate tree-level flavour-changing neutral currents), CP violation
is strongly suppressed. On the other hand, the most general Two-Higgs-Doublet
model (without Z_2 symmetry) would still allow for CP violation to be present
in the model, without being in conflict with the LHC data. Consequently, also
flavour-changing neutral currents would in general be expected. We briefly
sketch a strategy for measuring the remaining CP violation.
