A possible origin of the q=4/3 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.
