Hydrodynamics of Nuclear Collisions with Initial Conditions from Perturbative Qcd
We compute the longitudinal hydrodynamic flow in ultrarelativistic heavy ion collisions at √ 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. kari.eskola@c...
متن کاملClassical Initial Conditions for Nucleus-Nucleus Collisions
We present the results of an analytical calculation of the distribution of gluons in the state immediately following a heavy ion collision in the quasi–classical limit of QCD given by McLerran–Venugopalan model. We show that the typical transverse energy ET of the produced gluons is of the order of the saturation scale of the nuclei Qs, as predicted by Mueller. We demonstrate that due to multip...
متن کاملHot Spots and Turbulent Initial Conditions of Quark–Gluon Plasmas in Nuclear Collisions†
As a result of multiple mini-jet production, initial conditions of the QCD plasma formed in ultrarelativistic nuclear collisions may be inhomogeneous, with large fluctuations of the local energy density (hot spots), and turbulent, with a chaotic initial transverse velocity field. Assuming rapid local thermalization, the evolution of such plasmas is computed using longitudinal boost-invariant 3+...

متن کاملSmall x parton distributions and initial conditions in ultrarelativistic nuclear collisions
At the colliders RHIC and LHC, nuclei at the ultrarelativistic energies of 100 GeV/A and 2.7 TeV/A will be smashed together with the hope of creating an elusive and short-lived state of matter called the quark gluon plasma. The initial conditions which determine the dynamical evolution of the quark gluon matter formed in the central region after the collision depend crucially on the small x com...
