Minimal Flavour Violation and Anomalous Top Decays — •Sven Faller1, Thomas Mannel1, and Stefan Gadatsch21Theoretische Physik 1, Department Physik, Universität Siegen, D-57068 Siegen, Germany — 2Nikhef, National Institute for Subatomatic Physics, P.O. Box 41882, 1009 Amsterdam, Netherlands

Any experimental evidence of anomalous top-quark couplings will open a window to study physics beyond the standard model (SM). However, all current flavour data indicate that nature is close to ``minimal flavour violation", i.e. the pattern of flavour violation is given by the CKM matrix, including the hierarchy of parameters. In this talk we present results of the conceptual test of minimal flavour violation for the anomalous charged as well as flavour changing top-quark couplings. Our analysis is embedded in two-Higgs doublet model of type II (2HDM-II). Including renormalization effects, we calculate the top decay rates taking into account anomalous couplings constrained by minimal flavour violation.
