Description

Triangle singularity is one type of S-matrix singularities that appear in a triangle diagram when the interactions at all vertices can take place classically. On the one hand, it can produce a peaking structure mimicking a resonance, and thus its effects need to be carefully analyzed when identifying a new resonance; on the other hand, it can be used for precisely measuring the binding energy of a near-threshold particle. In this talk, I will review the effects of triangle singularities in various hadronic reactions.
