Description
In scattering experiments, a multitude of hadronic states was observed
already in the 50s and 60s of the last century. In order to explain
their abundance, a systematic approach was taken to search for an
underlying structure. Quantum chromodynamics was developed as a
theoretical description of these strongly interacting particles,
explaining the interactions between quarks and gluons, of which hadrons
are built. However, this cannot fully describe the observed spectrum of
states - in particular, the role of gluons and how they affect the
properties of the observed states has not been resolved. Especially the
discovery of quite a few unexpected "exotic" states in recent years has
highlighted the need for precise spectroscopic measurement to understand
the nature of the underlying interaction.
In this talk, it will be shown how we use experimental data from
large-scale experiments to perform dedicated studies of the production
and decay properties of hadrons in different processes and energy
ranges. These studies provide valuable information for the
classification and identification of the observed states.
