摘要：

We recall the diquark model of baryons and tetraquark states in both quark models and Schwinger-Dyson equations based on the diquark model. We slightly discuss the connection between quark models and the contact interaction model based on the Schwinger-Dyson and Bethe-Salpeter equations approach. Finally, by adopting the quark models ideas in the tetraquark picture, we calculate a mass value for the bb (b) over bar(b) over bar of 18.44
