Pseudoscalar top-Higgs coupling: Exploration of $\mathrm{CP}$-odd observables to resolve the sign ambiguity

Nicolas Mileo, Ken Kiers, Alejandro Szynkman +2

We present a collection of $\mathrm{CP}$-odd observables for the process $pp\to t\,\left(\rightarrow b {\ell}^+ ν_{\ell}\right) \bar{t}\,\left(\rightarrow \bar{b} {\ell}^-{\barν}_{…
