Probing anomalous t t ¯ Z $$ t\overline{t}Z $$ interactions with rare meson decays
Anomalous couplings of the Z boson to top quarks are only marginally constrained by direct searches and are still sensitive to new particle dynamics at the TeV scale. Employing an effective field theory approach we consider the dimension-six operators which generate deviations from the standard-model vector and axial-vector interactions. We …
