Effective operators in t-channel single top production and decay

Effective operators in t-channel single top production and decay

Abstract The production of a single top quark in the t-channel and its subsequent decay is studied at NLO accuracy in QCD, augmented with the relevant dimension-6 effective operators from the Standard Model Effective Theory. We examine various kinematic and angular distributions for proton-proton co...
