Abstract

We show that the five-fold constraints due to (1) the observed nuclear modification of heavy quark jets measured via non-photonic electrons RAAe(pT6GeV)R_{AA}^e(p_T \sim 6 {\rm GeV}) in central Au+Au collisions at 200 AGeV, (2) the "perfect fluid' elliptic transverse flow of low transverse momenta pions, v2(pT1GeV)v_2(p_T\sim 1 {\rm GeV}) reported for noncentral collisions, (3) the global pion rapidity density dNπ/dydN_\pi/dy, (4) the lattice QCD entropy density deficiency, S/SSBS/S_{SB}, of strongly coupled Quark-Gluon Plasmas (sQGP), and (5) a causal requirement are analytically correlated in a class of gauge/string gravity dual models of sQGP dynamics. Current RHIC/BNL and lattice QCD data are found to be remarkably compatible with these models if the t'Hooft and Gauss-Bonnet coupling parameters lie in the range λ1025\lambda\approx 10-25 and 0<λGB<0.090< \lambda_{GB}< 0.09. In addition, the observed five-fold correlation appears to favor color glass condensate over Glauber initial conditions within current systematic errors.
