Description
Over the past two decades, a large number of exotic states has been discovered at various accelerator facilities. Many of these states are located close to certain hadron-hadron thresholds and therefore can be considered as potential candidates for hadronic molecules. In this talk, we will review the classical Weinberg formalism that was developed to assess whether the deuteron is composite or elementary, and discuss how it can be extended to estimate compositeness of exotic states. We discuss how to treat the effective range parameters extracted from experimental line shapes when coupled channels are present and consider several applications.
