An interesting aspect of this solution is that the shapes of the rapidity distribution dN/dy and temperature distribution are coupled in the way that the larger the rapidity density, the smaller the effective temperature.
Simple solutions of relativistic hydrodynamics for longitudinally expanding systems
We are interested in the coupling between the measurable rapidity distribution and the rapidity dependence of the effective temperature in the transverse directions as obtained from our new family of solutions.
Simple solutions of relativistic hydrodynamics for longitudinally expanding systems
In case of a homogeneous rapidity distribution, dN/dy = C we recover Bjorken’s result that the effective temperature distribution is rapidity independent.
