Scattering resonances, the effect of two colliding particles forming a meta-stable quasi-bound state with a characteristic  sharp peak in the cross section is one of the most striking phenomena in hadronic, nuclear, and atomic experiments. 

However, despite being frequently observed, their theoretical description and prediction is non-trivial, especially when the resonating fragments are not elementary particles.

This five-lecture series aims to elaborate on this phenomenon as it is measured, theorized, numerical predicted, and interpreted in particle,
nuclear, and atomic fields. A balanced exposition of both, the theoretical understanding and the experimental relevance and interpretation from the various fields, shall identify common fallacies in the identification and quantification of resonance parameters.


The lectures are intended for a broad audience, and we would like to encourage especially the participation of early-career and Ph.D. researchers.
