ULtra-RelatIvistiCH HEavy IoNZ 2016

18 Jul 2016, 08:00 → 20 Jul 2016, 19:05 Europe/Zurich

222/R-001 (CERN)

For well over three decades, Ulrich Heinz has been a key player in the field of ultrarelativistic heavy-ion collision theory, making vital contributions to the experimental heavy-ion programs at CERN's SPS, at RHIC and at the LHC. His work spans a broad range of topics, including important contributions to thermal field theories, heavy flavors in quark-gluon plasma, Hanbury-Brown Twiss interferometry, and the hydrodynamic description of the quark-gluon plasma evolution. Ulrich turned 60 in 2015. We decided to organize this workshop to celebrate his 60th birthday and to dedicate it to the many areas of heavy ion physics that Ulrich had contributed to over the years. The workshop will thus discuss the recent achievements and current theoretical challenges of the phenomenology of ultra-relativistic heavy ion collisions with an emphasis on soft probes. 

Local organizers:  U.A. Wiedemann, Y. Foka, Y. Kovchegov, M. Lisa

11:00 → 11:30 A kinetic regime of hydrodynamic fluctuations and long time tails for a Bjorken expansion

We develop a set of kinetic equations for hydrodynamic fluctuations which are equivalent to nonlinear hydrodynamics with noise. The hydro-kinetic equations can be coupled to existing second order hydrodynamic codes to incorporate the physics of these fluctuations. We first show that the kinetic response precisely reproduces the renormalization of the shear viscosity and the fractional power ($\propto \omega^{3/2}$) which characterizes equilibrium correlators of energy and momentum for a static fluid. Then we use the hydro-kinetic equations to analyze thermal fluctuations for a Bjorken expansion, evaluating the contribution of thermal noise from the earliest moments and at late times. In the Bjorken case, the solution to the kinetic equations determines the coefficient of the first fractional power of the gradient expansion ($\sim 1/(\tau T)^{3/2}$) for the expanding system. Numerically, we find that the contribution to the longitudinal pressure from hydrodynamic fluctuations is larger than second order hydrodynamics for typical medium parameters used to simulate heavy ion collisions.
