Description

In the framework of Dyson-Schwinger equations, we present the first calculation of a four-body Bethe-Salpeter equation as required for the covariant description of tetraquarks. In a first approach we focus on the lightest tetraquark candidate, the $f_0(500)$, with an aim to determine the complete scalar nonet. Further investigations in this approach will focus on tetraquarks in the vector channel, mixing with $q\bar{q}$ mesons and the inclusion of charm quarks.
