Abstract

We present new, state-of-the-art predictions for the associated production of the SM Higgs boson with top quarks, computed in accordance with the recommendations of the LHC Higgs Working Group.The NNLO QCD predictions, derived through suitable approximations of the two-loop virtual contribution, are supplemented with soft-gluon resummation up to NNLL accuracy.Two distinct resummation frameworks are employed -one based on direct QCD and the other on soft-collinear effective theory -and their features are compared in detail.These results are further combined with the complete-NLO corrections, yielding the most precise SM predictions for this process to date.The relevant sources of theoretical uncertainties are thoroughly estimated and discussed.
