Constraints on AdS/CFT Gravity Dual Models of Heavy Ion Collisions
Abstract
We show that the five-fold constraints due to (1) the observed nuclear modification of heavy quark jets measured via non-photonic electrons in central Au+Au collisions at 200 AGeV, (2) the "perfect fluid' elliptic transverse flow of low transverse momenta pions, reported for noncentral collisions, (3) the global pion rapidity density , (4) the lattice QCD entropy density deficiency, , 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 and . In addition, the observed five-fold correlation appears to favor color glass condensate over Glauber initial conditions within current systematic errors.
