34 Key Issues for CBM in-depth study of onset of deconfinement EoS & transport coefficientsmedium modifications hadrons„never studied“ at SIS100/300 energies:charm: hidden & open, charm baryons(created early probe dense stage)dileptons & photons: penetrating probes(monitoring the dense stage, looking into fireball)fluctuations: higher moments sensitive to proxy of CEPcorrelations: size (temporal & spatial) measurements

36 Summary Cosmic Confinement/Hadronization: no imprints nucleons as remainder due small excess (= accident?)Nucleosynthesis: sensitive test of cosmic dynamicsabundancies of light elements is specific imprintNeutron Stars: quark cores seem possible(but hard to verify; need fine tuning of cold EoS)RHIC & LHC: sQGP seems w/o doubts, EoS from lattice QCD,sQGP = most perfect fluid: viscosities are small,energy scan at RHIC gives orientation (no rare probes)HADES&CBM at SIS100/300: exploration of phase diagram,rare & penetrating probes, closer link to hadron physics
