The School aims to summarize the latest heavy ion physics results, and encourage communication between the theory and experimental community. We will discuss some important new results that might be relevant particularly to hydrodynamics, flow and correlation analysis at RHIC and LHC. As usual a section will be devoted to recent results in lattice QCD, and we will cover recent results from STAR, PHENIX, ALICE and CMS. The School is organized such that students are particularly encouraged to participate (their fee is also waived). See more details on the web page of the school: http://zimanyischool.kfki.hu/12
