to ttH Production at the Large Hadron Collider The Large Hadron Collider (LHC) of the European Organization of Nuclear Research (CERN) opens a new era for investigating highenergy particle interactions, since an experimental study of proton–proton collisions with energies up to 14TeV becomes possible. Such processes allow for the production of a Higgs boson which is an important constituent of the Standard Model of Elementary Particle Physics. The properties of the Higgs boson can be analysed, for example, in the ttH production channel where the Higgs boson is produced in association with a top–antitop quark pair. Especially, the direct measurement of the Higgsboson coupling to the top quark, which is large in the Standard Model due to the large topquark mass, plays a crucial role in establishing the Standard Model Higgs boson or pointing to some extended models with possibly more than one Higgs boson. For a proper experimental analysis, precise theoretical predictions for total and differential cross sections are needed. Aside from small effects on the total cross section, nexttoleadingorder electroweak corrections are significant in differential distributions, in particular for kinematics with large transverse Higgs momenta. Besides the calculational framework of these corrections and the methods used for the evaluation, numerical results are presented and discussed including, in particular, differential distributions of the outgoing particles.
