un 2 00 8 Causal relativistic hydrodynamics for viscous fluids ‡
We report on recent results from VISH2+1, a code that solves the relativistic Israel-Stewart equations for causal viscous hydrodynamics for heavyion collisions with longitudinal boost invariance. We find that even “minimal” shear viscosity η/s = ~/(4π) leads to a large reduction of elliptic flow compared to ideal fluid dynamics. We explore systematically the sensitivity of this reduction to the...
متن کاملCausal viscous hydrodynamics in 2 + 1 dimensions for relativistic heavy-ion collisions
We explore the effects of shear viscosity on the hydrodynamic evolution and final hadron spectra of Cu + Cu collisions at ultrarelativistic collision energies, using the newly developed (2 + 1)-dimensional viscous hydrodynamic code VISH2+1. Based on the causal Israel-Stewart formalism, this code describes the transverse evolution of longitudinally boost-invariant systems without azimuthal symme...
متن کاملDispersive hydrodynamics in viscous fluid conduits.
The evolution of the interface separating a conduit of light, viscous fluid rising buoyantly through a heavy, more viscous, exterior fluid at small Reynolds numbers is governed by the interplay between nonlinearity and dispersion. Previous authors have proposed an approximate model equation based on physical arguments, but a precise theoretical treatment for this two-fluid system with a free bo...

متن کاملGrape { Dilepton a Generator for Dilepton Production in Ep Collisions Title of Program: Grape-dilepton (v1.1)
GRAPE-Dilepton is a Monte Carlo event generator for dilep-ton production in ep collisions. The cross-section calculation is based on the exact matrix elements in the electroweak theory at tree level. The dilepton productions via , Z 0 , Z 0 Z 0 collisions and via photon internal conversion are taken into account. In addition, the eeects of the Z 0 on/oo-shell production are also included. The r...
