Description
Since the experimental discovery of the first exotic hadrons in 2003, these
states have attracted considerable attention from both the theoretical and ex-
perimental communities. Over the past two decades, an increasing number
of exotic hadrons—most notably tetraquarks and pentaquarks—have been ob-
served at experimental facilities around the world.
Various theoretical approaches can be employed to study the properties of ex-
otic hadrons. Among these, functional methods combining Bethe–Salpeter and
Dyson–Schwinger equations, provide a powerful and fully relativistic framework.
In recent years, substantial progress has been made in extending this framework
to the study increasingly complex multiquark systems.
In this talk, I will give an overview of the functional framework and its
applications to the calculation of exotic hadron spectra. I will discuss recent
results for tetraquarks and pentaquarks and illustrate how the framework can
also provide insight into the internal composition of these states
