Effective direct and indirect top constraints — Maikel De Vries, Thomas Konstandin, •Matthias Schlaffer, and Andreas Weiler — DESY, Hamburg, Germany

We use an effective field theory approach to study in a systematic way the effects of anomalous top couplings. We focus in particular on CP-violating operators and find constraints on them from direct and indirect measurements. This has important implications for new physics models and the search for their signatures at the LHC.
