Subject: Extracting Bulk Properties of the Quark Gluon Plasma from Experiment

Relativistic heavy ion collisions at RHIC (Relativistic Heavy Ion Collider at Brookhaven) and at the LHC produce environments where energy densities reach tens of GeV per cubic fm, well above the threshold for producing the quark gluon plasma. However, given the short time scales, ~10^{-22} sec, and the short distance scales, ~10^{-14} m, measurements are relegated to recording the momenta of some fraction of the outgoing particles. Thus, inferring the properties of the QGP from experiment requires a careful comparison of experimental results to theoretical models. I will review some examples for how measurements constrain the equation of state, chemistry, and transport coefficients of the QGP. Finally, I will review strategies for statistically rigorous model-data comparison. These techniques account for the numerically intensive nature of the models and the heterogeneous character of the peta-scale data sets.
