Findings

Identifies the role of the diquark in top quark asymmetry

Connects the diquark to supersymmetric scalar classification

Suggests a theoretical origin for the diquark

Abstract

Between the new physics candidates proposed to explain the $t \bar t$ asymmetry measured in the Tevatron, there are some scalar diquarks with electric charge +4/3. This kind of diquark is also needed to classify all the scalars of the supersymmetric standard model, with three generations, under a global flavour symmetry.
