Hydrodynamic collectivity and viscosities 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 at Pb+Pb $\sqrt{s_{\rm NN}}=2.76$ 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 the detailed information of 
the QGP bulk property, without being smeared by the final state interactions. 

Furthermore we apply our hydrodynamic model  to the small systems such as p+p and p+Pb collisions 

and discuss applicability of the hydrodynamics to the systems from quantitative analyses of single 

particle spectra and collective flows.
