Relativistic Hydrodynamics at RHIC and LHC

Recent development of a hydrodynamic model is discussed by putting an emphasis on realistic treatment of the early and late stages in relativistic heavy ion collisions. The model, which incorporates a hydrodynamic description of the quark-gluon plasma with a kinetic approach of hadron cascades, is applied to analysis of elliptic flow data at the Relativistic Heavy Ion Collider energy. It is predicted that the elliptic flow parameter based on the hybrid model increases with the collision energy up to the Large Hadron Collider energy.Comment: 8 pages, 7 figures, talk given at YKIS Seminar on New Frontiers in QC

Perfect fluidity of sQGP core and dissipative hadronic corona

We can establish a new picture, the perfect fluid sQGP core and the dissipative hadronic corona, of the space-time evolution of produced matter in relativistic heavy ion collisions at RHIC. It is also shown that the picture works well also in the forward rapidity region through an analysis based on a new class of the hydro-kinetic model and is a manifestation of deconfinement.Comment: 4 pages, 2 figures, talk given at Particles and Nuclei International Conference (PANIC05), Santa Fe, New Mexico, 24-28 Oct 200
