37. 37K. Peters - Panda and Charmonium Prospects at FAIR Summary and Outlook It’s an amazing time in charm spectroscopy many new states – but no coherent picture Where are gluonic excited charmonia (hybrids) spectrum, widths and decay channels What are the new D sJ states and the X(3872) what are their properties like width and decay channels Interaction with nuclear matter mass shifts, broadening and attenuation Only high precision experiments can finally help to solve the puzzle like Panda @ HESR @ GSI
