Observables from a solution of (1+3)-dimensional relativistic hydrodynamics

In this paper we analyze a (1+3)-dimensional solution of relativistic hydrodynamics. We calculate momentum distribution and other observables from the solution and compare them to measurements from the Relativistic Heavy-Ion Collider (RHIC). We find that the solution we analyze is compatible with the data. In the last several years many numerical models were tested, but it is the first time that an exact, parametric, (1+3)-dimensional relativistic solution is compared to data.
