Exotic open and hidden charm states

Abstract

We discuss recent theoretical developments in the context of charmed exotics with special emphasis on hadronic molecules. Especially we discuss, how these could be identified from experimental as well as lattice QCD observables.

Invited talk at CHARM 2009 (International Workshop on Charm Physics), Leimen, Germany, 20-22 May 2009
