Evaluating the b2 and b4 angular observables in the ttbar h rest frame, instead of the lab frame, reduces by about 250 inverse femtobarns the integrated luminosity needed to exclude a pure CP-odd top-quark Yukawa coupling.

abstract
We present predictions for the production cross section of a Standard Model Higgs boson in association with a top-antitop pair at next-to-leading order accuracy using matrix elements obtained from the HELAC-Oneloop package. The NLO prediction was interfaced to the PYTHIA and HERWIG shower Monte Carlo programs with the help of POWHEG-Box, allowing for decays of massive particles, showering and hadronization, thus leading to final results at the hadron level.

The Role of the $t{\bar t}h$ Rest Frame in Direct Top-Quark Yukawa Coupling Measurements
Evaluating the b2 and b4 angular observables in the ttbar h rest frame, instead of the lab frame, reduces by about 250 inverse femtobarns the integrated luminosity needed to exclude a pure CP-odd top-quark Yukawa coupling.
