Description
With the increasing experimental discoveries of multiquark states in recent years, few-body problems have become increasingly important in hadron physics. The complex scaling method provides an effective approach to study bound and resonant states in few-body systems. In this talk, I will start from the leptonic systems with cleaner interactions, and give particular attention to tetralepton systems, which share important similarities with tetraquark states. I will then draw a comparison with tetraquark systems, illustrating how the additional color degrees of freedom in QCD reshape the spectrum.
