Abstract
Entropy balance is very important at ultra-high energy HIC’s, because there is not even approximate thermalisation there. Only a minor fragment of the incoming kinetic energy will be turned into “heat”, so internal energy, while the thermodynamic state variable is internal energy, not the total one. Here an approach is discussed calculating entropy directly, in a continuum physics scenario.
