NICA: Theoretical Overview

There are strong reasons to bleive that the energy region covered by the Nuclotron-based Ion Collider fAcility (NICA) is an extremely interesting one. We present an overview of theoretical proposals in relativistic heavy ion collisions and show where more and better measurements are needed. The theoretical understanding can be clarified by covering the energy region available to NICA. It would be helpful to determine the strangeness content by covering the full phase space (\(4\pi \)) to determine the thermodynamic parameters.
