Structure of open-flavour four-quark states in the charm and bottom region
Joshua Hoffer, Gernot Eichmann, Christian S. Fischer
We present quantitative results for masses and the internal structure of four-quark states with two heavy quarks, i.e. with and $q,q' \in \{u…

Functional methods for hadron spectroscopy
Gernot Eichmann, Christian S. Fischer, Joshua Hoffer
We summarize recent results for four-quark states with hidden and open flavor obtained from a four-quark Bethe-Salpeter/Faddeev-Yakubowsky equation. The approach dynamically predic…
