A global approach to top-quark flavor-changing interactions
Gauthier Durieux, Fabio Maltoni, Cen Zhang
We adopt a fully gauge-invariant effective-field-theory approach for parametrizing top-quark flavor-changing-neutral-current interactions. It allows for a global interpretation of…
Automatic computations at next-to-leading order in QCD for top-quark flavor-changing neutral processes
Celine Degrande, Fabio Maltoni, Jian Wang +1
Computations at next-to-leading order in the Standard Model offer new technical challenges in presence of higher dimensional operators. We introduce a framework that, starting from…
Top couplings and new physics: theoretical overview and developments
Cen Zhang
Top-quark physics has entered the precision era. In this talk we discuss the theoretical ingredients required for a global approach to the complete set of top-quark couplings at NL…
Effective approach to top-quark decay and FCNC processes at NLO accuracy
Cen Zhang
The top quark is expected to be a probe to new physics beyond the standard model. Thanks to the large number of top quarks produced at the Tevatron and the LHC, various properties…
Effective field theory approach to top-quark decay at next-to-leading order in QCD
Cen Zhang
We present analytical results for top-quark decay processes, in an effective field theory beyond the Standard Model, at next-to-leading order in QCD. We parametrize new physics eff…
Effective Field Theory Beyond the Standard Model
Scott Willenbrock, Cen Zhang
We review the effective field theory approach to physics beyond the Standard Model using dimension-six operators. Topics include the choice of operator basis, electroweak boson pai…
