EMMI Hadron Physics Seminar

Deciphering XYZ

Description

I discuss the charmonium-like exotic so-called XYZ states. A number of these states have been found recently at electron-positron colliders and at LHC indicating existence of a rich spectrum of new hadronic systems. The `internal dynamics' is likely different in different exotic resonances, with some being possibly advantageous for studies in p¯p (and also p¯n) collisions. I summarize the current expectations for such studies and their possible implications for understanding the new multiquark structures.
