Developing QCD Phase Diagram new phase diagram old phase diagram pair dissociation line T weakly coupled QGP, ideal gas viscous fluid perfect fluid LHC RHIC s. QGP FAIR hadrons viscous fluid CSR BEC BCS New Phenomena: from ideal gas (coupling = 0) to perfect fluid (viscosity = 0), strongly coupled quark-gluon plasma, QCD phases at high density (related to cold atom gas, ……) non-perturbative QCD at RHIC and LHC ! 1
What We Learned From the Workshop (1) 1) particle production PBM, 2008 Ko Ko thermal production of charm quarks: 20% contribution, sensitive to T and Mc enhancement of charmed baryons Levai Papp high Pt suppression, EMC prediction for LHC soft/hard overlap at intermediate Pt, need precise measurement 2
What We Learned From the Workshop (2) 2) scaling, fluctuation, and correlation Yang n=13. 2 Chen developed in the partonic stage ! valid for any collisions at ALL energies, ALL centralities and All rapidities STAR 0 -10% Au+Au Total b Zhang Fu: a constant F-B correlation due to geometry fluctuation F-B also by Yan dihadron spectra 3
What We Learned From the Workshop (3) 3) charmonium production Lee Xu Zhuang From G =constraint-Dm (Stark effect) QCD sum rule constraint with DG=0 G Lee near-side DD correlation at LHC the sudden change in gluon condensates leads to a a critical behavior of charmonium mass and width 4
What We Learned From the Workshop (4) 4) quark polarization Liang more significant at LHC ! a more precise theoretical frame is presented by Wang 5
What We Learned From the Workshop (5) 5) low energy Xiao beam energy less than 0. 5 Ge. V/u is favorable for Esym( ) study. 6
What We Learned From the Workshop (6) 6) phase diagram Liu Mu p. NJL calculation the peak is similar to the calculation in Ad. S/CFT calculation 7
most important sentence of this workshop LHC is well equipped for heavy ion study ! pair dissociation line s. QGP BEC SPS RHIC BCS ? LHC 8
