Description
A promising area of development in QCD research is extending beyond the well-studied boost-invariant or (2+1)D picture of QGP evolution and into (3+1)D. Doing so offers a powerful means of further constraining the validity and the parameters of successful collision models and thus allows us to refine our knowledge of the properties of the QGP. However, the extra dimension also introduces challenging new degrees of freedom, particularly in the initial conditions, and exacts a high computational cost in hydrodynamics.
Seeking to facilitate (3+1)D analyses, we have developed TRENTo-3D, a fast, parametric model of 3D initial-state geometry. We have tested its validity through a large-scale calibration that we wish to report on in this contribution. For computational efficiency this validation implemented a (1+1)D linearized approximation of ideal hydrodynamics, which restricted the set of observables that can be computed with small uncertainties. We will present the results of this first calibration and preview a second, ongoing effort to perform a calibration featuring a full (3+1)D viscous hydrodynamic evolution and a much broader set of observables.
