Query: Revisiting Bayesian constraints on the transport coefficients of QCD   Multistage models based on relativistic viscous hydrodynamics have proven
successful in describing hadron measurements from relativistic nuclear
collisions. These measurements are sensitive to the shear and the bulk
viscosities of QCD and provide a unique opportunity to constrain these
transport coefficients. Bayesian analyses can be used to obtain systematic
constraints on the viscosities of QCD, through methodical model-to-data
comparisons. In this manuscript, we discuss recent developments in Bayesian
analyses of heavy ion collision data. We highlight the essential role of
closure tests in validating a Bayesian analysis before comparison with
measurements. We discuss the role of the emulator that is used as proxy for the
multistage theoretical model. We use an ongoing Bayesian analysis of soft
hadron measurements by the JETSCAPE Collaboration as context for the
discussion.
