Query: Pseudoscalar top-Higgs coupling: Exploration of $\mathrm{CP}$-odd
  observables to resolve the sign ambiguity   We present a collection of $\mathrm{CP}$-odd observables for the process
$pp\to t\,\left(\rightarrow b {\ell}^+ \nu_{\ell}\right)
\bar{t}\,\left(\rightarrow \bar{b} {\ell}^-{\bar{\nu}}_{\ell}\right)\,H$ that
are linearly dependent on the scalar ($\kappa_t$) and pseudoscalar
($\tilde{\kappa}_t$) top-Higgs coupling and hence sensitive to the
corresponding relative sign. The proposed observables are based on triple
product (TP) correlations that we extract from the expression for the
differential cross section in terms of the spin vectors of the top and antitop
quarks. In order to explore other possibilities, we progressively modify these
TPs, first by combining them, and then by replacing the spin vectors by the
lepton momenta or the $t$ and $\bar{t}$ momenta by their visible parts. We
generate Monte Carlo data sets for several benchmark scenarios, including the
Standard Model ($\kappa_t=1$, $\tilde{\kappa}_t=0$) and two scenarios with
mixed $\mathrm{CP}$ properties ($\kappa_t=1$, $\tilde{\kappa}_t=\pm 1$).
Assuming an integrated luminosity that is consistent with that envisioned for
the High Luminosity Large Hadron Collider, using Monte Carlo-truth and taking
into account only statistical uncertainties, we find that the most promising
observable can disentangle the "$\mathrm{CP}$-mixed" scenarios with an
effective separation of $\sim 19\sigma$. In the case of observables that do not
require the reconstruction of the $t$ and $\bar{t}$ momenta, the power of
discrimination is up to $\sim 13\sigma$ for the same number of events. We also
show that the most promising observables can still disentangle the
$\mathrm{CP}$-mixed scenarios when the number of events is reduced to values
consistent with expectations for the Large Hadron Collider in the near term.
