We present the calculation of scalar and pseudoscalar Higgs production in association with a top-antitop pair to the next-to-leading order (NLO) accuracy in QCD, interfaced with parton showers according to the MC@NLO formalism. We apply our results to the cases of light and very light Higgs boson production at the LHC, giving results for total rates as well as for sample differential distributions, relevant to the Higgs, to the top quarks, and to their decay products. This work constitutes the first phenomenological application of aMC@NLO, a fully automated approach to complete event generation at NLO in QCD.

    hep-ph 2026-03 conditional novelty 6.0 of 10

    First NNLO+PS (MiNNLOPS) generator for ttH production, combining soft-Higgs and high-energy approximate two-loop amplitudes pointwise, with one-loop-level validation.

    hep-ph 2026-06 unverdicted novelty 5.0 of 10

    Phenomenological LHC study finds sensitivity to light spin-1 DM mediators in ttbar events and discrimination power from CP-sensitive angular observables in dileptonic final states.

  5. Analyzing $t\bar{t}Z$-couplings at the future $e^-p$ collider

    hep-ph 2025-07 conditional novelty 4.0 of 10

    At a future LHeC, the azimuthal angle between the scattered electron and the lepton from top decay could constrain the ttbarZ axial coupling to about 8% and the vector coupling to about 68% precision at 95% CL with 10...

  6. The Role of the $t{\bar t}h$ Rest Frame in Direct Top-Quark Yukawa Coupling Measurements

    hep-ph 2019-09 conditional novelty 4.0 of 10

    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.
