Description
The latest experimental data from ALICE@LHC confirm that the hydrodynamical simulations of the ultra-relativistic heavy ion collisions are very successful in describing these reactions. One of the most important elements of such a hydrodymamical model is the initial state for further hydro evolution. Unfortunately at the moment there is no unambiguous model describing initial states of the energetic heavy ion collisions.
I my talk I will argue that from the very general principles, like linear and angular momentum conservation, we can expect to form tilted and rotating initial state. I will present initial states generated by the Effective String Rope model [1] for RHIC and LHC heavy ion reactions; and compare it with some other models which intent to simulate/calculate initial state for hydrodynamical simulation, including for example CGC based model [2].
The key question of the talk is what are the observable consequences of such a tilted and rotating initial state?
