Abstract: (arXiv)

We compute the longitudinal hydrodynamic flow in ultrarelativistic heavy ion collisions at

\sqrt{s}

= 5500 GeV by using boost non-invariant initial conditions following from perturbative QCD. The transfer of entropy and energy from the central region to larger rapidities caused by boost non-invariance is determined and the associated decrease in the lifetime of the system is estimated.
