Within  m < 1 MeV of the DD* threshold S-wave molecular state? Large cross-section – it is charmonium χ c1 (2P)?- (S.S. Gershtein, A.K. Likhoded, A.V. Luchinsky Phys.Rev. D74 (2006) ) - For molecule should be lower by factor 10^2) Probably two narrow states (CDF) Charge partner? – not in the mass window neither in width

OTHER PHYSICS June Nucleon Structure from electromagnetic processes The extension of form factor measurements to the so called time-like region separating the magnetic and electric components can be performed with an order of magnitude improvement clean identification of dileptons can be used to measure a whole series of other electromagnetic processes like for example Drell-Yan in order to get access to the transverse spin structure functions. Study hyper-nuclei (including - double) and charm-nuclei, when the strange (one or two) or charmed particle "implanted" into the nuclei instead of the usual nucleon Hadrons in nuclear matter These items will be reported tomorrow by Marco Destefanis

PANDA AT NUPECC COMMUNITY June 2013V. MOCHALOV, HADRON STRUCTURE The long-range plan of NUPECC for the European hadron physics community of the year 2010 identifies three major areas in hadron physics as prime goals for the future. Those are: ‘Hadron Spectroscopy’ ‘Hadron Structure’ and ‘Hadronic Interactions’. The PANDA experiment by design can contribute to all of these

CONCLUSIONS June 2013V. MOCHALOV, HADRON STRUCTURE The PANDA experiment will have a great potential for discovery in addition to the LHC at a relatively high-energy antiprotons and, at the same time, due to the energy scan mode will determine masses and widths of the resonances with an accuracy of a linear collider. In addition to high-intensity (up to 2х10 7 interactions), beam of antiprotons would be unprecedented in the degree of monochromatic, the expected level of  p/p down to 10 -5, which will allow the study of strong interactions with high precision. PANDA detector is created using the most modern technology and provides a registration and identification of neutral and charged particles to nearly the full solid angle and energy range up to 15 GeV. A commissioning of PANDA and the first data taking is planned for 2018.
