Phenomenological studies of top-quark properties at hadron collider


The main goal of the project is to improve our current understanding of top-quark properties using experimental input obtained in hadronic collisions. Top-quark physics is one of the central research topics at the Large Hadron Collider (LHC). Since the project focuses on Standard Model properties of the top quark, a central aspect is to improve the availability of theoretical results within the Standard Model. Furthermore, new observables will be investigated, allowing a more precise determination of top-quark properties within the experimental analysis. In addition, the extension of the so-called matrix element method to include next-to-leading order QCD corrections shall be studied. The precise determination of top-quark properties allows to test the mechanism of electro weak symmetry breaking at
high energies with unprecedented accuracy.
