Electroweak NLO corrections to tt H production at the LHC — •Michael Kordovan and Stefan Dittmaier — Albert-Ludwigs-Universität Freiburg (Germany)

The Higgs-production process pp → tt H allows for a direct measurement of the Higgs-boson Yukawa coupling to the top quark and is therefore predestined for establishing the Standard Model Higgs boson or for giving indication for some extended Higgs sector. Aside from small effects on the total cross section, NLO electroweak corrections are significant in differential distributions, in particular for kinematics with large transverse Higgs momenta. Nevertheless, the NLO electroweak corrections to this Standard Model channel are still unknown. Remedying this shortcoming the calculation of the electroweak NLO corrections is in progress now. First partial numerical results are presented and discussed including, in particular, rapidity and transverse-momentum distributions of the outgoing particles.
