This seminar has been postponed from April 2020 to May 2021 due to the corona pandemic.

Fifty-six years after the inception of the quark model and forty-five years after the development of QCD the excitation spectrum of confined systems of quarks still provides surprises. Across all flavour sectors, and in mesons as well as in baryons, exotic phenomena have been observed, which challenge our current understanding of the emerging dynamics of the strong interaction.

Although a lot of information on potential multi-quark systems has been gathered and first evidence for gluonic excitions is available, the fundamental question on the nature of these phenomena is only just beginning to be answered.

This workshop will bring together the hadron spectroscopy communities at high- and medium-energy experiments as well as theoreticians.

We will discuss how complementary approaches to studying the hadron spectrum will offer new opportunities in the next years. The goal is to identify synergies between the communities, which can lead to a better understanding of hadronic processes.

We explicitly want to encourage discussion that probes the boundaries and limits of current practice, and explore possible new routes  of investigation. The large data samples, which are being collected, put an increasing demand on the quality of the analysis techniques required to extract well defined observables from the data. We will explore how to facilitate close collaboration of theorists and experimentalists on the development of such new techniques.

The conference language will be English. The Wilhelm and Else Heraeus-Foundation bears the cost of full-board accommodation for all participants.
