GSI has proposed to build a new international accelerator facility for beams of ions and antiprotons. One of the main topics will be investigations into the structure of hadrons and their interaction with the nuclear medium using cooled antiproton beams of unprecedented quality and intensity in the momentum range of 1.5 to 15 GeV/c stored in the High Energy Storage Ring (HESR). The physics program consists of the following research directions: Charmonium spectroscopy: precision measurements of mass, width, and decay branches of all charmonium states; establishment of the existence of QCD-predicted gluonic excitation of hadrons (i.e. hybrids and glueballs) in the charmonium mass range (3-5 GeV); search for modifications to the properties of charm mesons in the nuclear environment; study of single and double hypernuclei by precision γ-ray spectroscopy. Furthermore, many additional interesting physics topics can be addressed with increasing luminosity of the facility.
