The top quark, the heaviest known elementary particle, is an excellent probe of the fundamental interactions at (sub)attometer distances. Theoretical investigations of the production and decay of these quarks are essential for the analysis of corresponding experimental data. We plan to make precise predictions of the production of single top (anti)quarks at the Tevatron and the LHC, and we envisage, in this context, to achieve new contributions to the theory of heavy quark jets. In addition, possible new interactions of top quarks will be analyzed.

The top quark, which is the heaviest (elementary) particle known to date, is an excellent probe of the fundamental interactions at high energies. Present and future analyses of top quark events at colliders require precise predictions of the production and decay of these particles within the standard model (and also non-standard models) of the particle physics. Based on the significant progress that was made in this project during the previous funding period, we shall continue the theoretical investigation of the pair production of top quarks and their interactions.
