Characterization of the initial state and QGP medium from a combined Bayesian analysis of LHC data at 2.76 and 5.02 TeV
Abstract
Here, we perform a global Bayesian analysis of a modern eventbyevent heavyion collision model and LHC data at √s = 2.76 and 5.02 TeV. After calibration, the model simultaneously describes multiplicity, transverse momentum, and flow data at both beam energies. We report new constraints on the scaling of initialstate entropy deposition and QGP transport coefficients, including a quantitative estimate of the temperaturedependent shear viscosity (η/s)(T).
