Summary & OutlookSummary & Outlook
Investigation of charmed hadrons and their interaction with matter is a mandatory task for the next decade
The antiproton facility HESR @ GSI addresses many important questions
A high performance storage ring and detector are envisaged to utilize a luminosity of L=2 x 1032 cm-2s-1
