Radiation effects in electroweak processes at current and future hadron colliders

After the discovery of the Higgs boson accurate measurements confronted with high-precision calculations are essential to reveal whether all properties of this new particle are compatible with the expectations of the Standard Model. Complementary to information gained in the Higgs sector itself, crucial constraints on the structure of the Standard Model are provided by a precision analysis of the gauge boson sector. While the status of the required higher-order perturbative calculations in terms of the strong interaction is quite advanced, electroweak corrections have received less attention in the past. However, their impact can be considerable at currently accessible collider energies already, and is expected to become even more significant at future hadron colliders operating at yet higher energies. With this proposal we envisage to close that gap for a selection of phenomenologically particularly important electroweak processes at hadron colliders. For these we plan to develop Monte-Carlo programs that permit, at the same time, the computation of strong and electroweak corrections and their matching with QCD and QED shower generators. This will allow us to obtain accurate yet realistic predictions for experimentally accessible observables at current and future hadron colliders. With our new tools we will perform detailed phenomenological studies to quantify the interplay of various types of radiation effects in different energy regimes.
