Study of top quark fcnc couplings at future colliders

Abstract

Top quark is the only quark available within the Standard Model SM of particle physics which decays before forming bound state with other quarks including its anti particle This property of the top quark makes it unique as it provides a way to study the properties of a bare quark The SM predicts branching ratio BR t Wb 226 8225 160 100 On the other hand the Flavor Changing Neutral Current FCNC interactions are forbidden within the SM with possible contributions arising at higher order corre...
