Description
I will discuss the state of the art on the exotic charmed mesons (XYZ) discovered since 2003, which do not fit in the standard ccbar spectrum. I will revise the clues that have been collected on their internal structure starting from the experimental information available on their production and decay mechanisms. Finally I will consider some processes in which XYZ could pay a role as intermediate states: what kind of additional information can we learn from that?
