Studying the Strong Interaction Non-perturbative regime of QCD Quarks are confined Hadron mass >> Σ quark masses Self-interaction among gluons
Integration of PANDA in FAIR FAIR (Facility for Antiproton and Ion Research) proton Linac 100/300 Tm Synchrotron HESR (High Energy Storage Ring) 50 Tm storage ring 1 to 15 GeV/c antiprotons high luminosity mode: L= 2·10 32 cm -2 s -1 high resolution mode: p/p ~ electron cooling/stochastic cooling internal target HESR Super FRS NESR CR production target
Charmonium Spectroscopy advantage in : direct formation of all charmonium states Crystall Ball On PANDAs menu: Systematic study of the complete spectrum (high statistics, high precision) h c Radiative deexcitations States above the DDbar- threshold
Glueballs Morningstar, Peardon, PRD 60(99) UKQCD, Bali et al., PLB 309(93)378 Mixing with other states maybe less in charm quark mass region Clean signal: exotic quantum numbers
(Charmed) Hybrids Mixed state of a quark- antiquark pair and a gluon Non-exotic hybrids: formation, production Exotic hybrids: production (J PC = 0 +-, 1 -+, 2 +- ) Exotic charmonia: 3-5 GeV/c 2
Charmed Hadrons in Medium Evidences for modifications in medium (charged kaons, pions) D-meson: heavy quark, light antiquark MeV/c 2 splitting Large charm quark mass little sensitivity to quark condensate gluon condensate m = 140 MeV/c 2 for Ψ(3770)
