In the Standard Model, the Higgs boson is predicted to be a scalar particle. However, a possible admixture of a $\cal{CP}$-odd component has yet to be excluded experimentally.
In this talk, I will present predictions for the associated production of a top-quark pair and a stable Higgs boson $pp\to e^+\nu_e\,\mu^-\bar{\nu}_\mu\,b\bar{b}\,H$ with possible mixing between $\cal{CP}$-even and $\cal{CP}$-odd states at NLO in QCD. I will compare the behaviour of the $\cal{CP}$-even, -odd and -mixed scenarios for the integrated fiducial cross sections and several key differential distributions. In addition, I will show that both NLO corrections and off-shell effects play an important role.
