Temperature dependence of transport coefficients of QCD in high-energy heavy-ion collisions

Using our developed new relativistic viscous hydrodynamics code, we investigate the temperature dependence of shear and bulk viscosities from comparison with the ALICE data: single-particle spectra and collective flows of Pb+Pb root(s)(NN) = 2.76 TeV collisions at the Large Hadron Collider. We find that from the comprehensive analyses of centrality dependence of single-particle spectra and collective flows we can extract detailed information on the quark-gluon plasma bulk property, without the information being smeared by the final state interactions.
