A complete calculation of Shear Viscosity in Strongly Interacting matter
… the unexplored field of the high temperature T Quark-Gluon Plasma, with new discoveries that seem to enforce the hypothesis that such an exotic state of Strongly Interacting matter can indeed exist, making it an established fact. Things in the finite baryon density opposite regime are much …

Paarproduktion schwerer Quarks in e+ e- -Kollisionen: QCD-Strahlungskorrekturen für die Quark-Antiquark-Beiträge zur Ordnung alpha s 2
… amplitude of a virtual Z-boson into a heavy quark anti-quark pair is decomposed into four dimensionless form factors which are extracted from the decay amplitude with appropriate projectors. The resulting 1- and 2-loop integrals are reduced to linear combinations of known master integrals …

Korrekturen der schwachen Wechselwirkung zur hadronischen Topquark-Paarproduktion
… of order alpha_s^2 alpha to hadronic top-quark pair production. The one-loop weak corrections to top antitop production due to gluon fusion and uark antiquark annihilation are computed. Also the order alpha_s^2 alpha corrections to top antitop production due to quark gluon and antiquark …

Studies at the CMS experiment on silicon microstrip module defects and on photon identification in semileptonic tt-events
… containing photons that are radiated off top-quarks. A signature based Monte Carlo analysis reveals that the separation of the ttbar-events from the non-ttbar background (W + Jets, Z + Jets, di-boson, Photon + Jets, and QCD-multijet events) is possible. The resulting photon energy spectra are …

Top quark mass measurement in the Lepton+Jets channel using full simulation of the CMS detector
… TeV the production cross section for top/antitop quarks (ttbar) is about 830 pb (NLO). The top quarks almost exclusively decay into a W boson and a b quark via the weak interaction. In about 44.4% of all events one of the top quarks decays into a lepton and neutrino while the other one decays into …

Third-order QCD corrections to heavy quark pair production near threshold
The measurement of the top quark mass is an important task at the future International Linear Collider. The most promising process is the top quark pair production in the threshold region. In this region the top quarks behave non-relativistically and a perturbative treatment using effective field …
