Deciphering XYZ

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 $\bar p p$ (and also $\bar p n$) collisions. I summarize the current expectations for such studies and their possible implications for understanding the new multiquark structures.
