Description

A recently found new family of exact solutions of 1+1 dimensional relativistic hydrodynamics will be presented, and its applications to describe the pseudorapidity density, the HBT radii and the estimation of the initial energy density in proton-proton and heavy ion collisions at LHC, RHIC and SPS energies will be reviewed. The talk will focus on a recently discovered signal of a non-monotonic behaviour of the initial energy densities in heavy ion collisions at RHIC energies.
