Title: Bulk viscous effects on flow and dilepton radiation in a hybrid approach

Abstract

Starting from IP-Glasma initial conditions, we investigate the effects of bulk pressure on low mass dilepton production at the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC) energies. Though thermal dilepton v₂ is affected by the presence of both bulk and shear viscosity, whether or not these effects can be measured depends on the dilepton “cocktail” contribution to the the low mass dilepton v₂. Furthermore combining the thermal and “cocktail” dileptons, the effects of bulk viscosity on total dilepton v₂ is investigated.

Dilepton radiation and bulk viscosity in heavy-ion collisions

Journal Article Vujanovic, Gojko ; Paquet, Jean-François ; Shen, Chun ; ... - Nuclear and Particle Physics Proceedings

Starting from IP-Glasma initial conditions, we explore in this research the effects of bulk pressure on thermal dilepton production at the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC) energies. Though results of the thermal dilepton v₂ under the influence of both bulk and shear viscosity is presented for top RHIC energy, more emphasis is put on LHC energy where such a calculation is computed for the first time. The effects of the bulk pressure on thermal dilepton v₂ at the LHC are explored through bulk-induced modifications on the dilepton yield.

Investigating the temperature dependence of the specific shear viscosity of QCD matter with dilepton radiation

Journal Article Vujanovic, Gojko ; Denicol, Gabriel S. ; Luzum, Matthew ; ... - Physical Review. C

This work reports on investigations of the effects on the evolution of viscous hydrodynamics and on the flow coefficients of thermal dileptons, originating from a temperature-dependent specific shear viscosity η/s(T) at temperatures beyond 180 MeV formed at the Relativistic Heavy-Ion Collider (RHIC). Here we show that the elliptic flow of thermal dileptons can resolve the magnitude of η/s at the high temperatures, where partonic degrees of freedom become relevant, whereas discriminating between different specific functional forms will likely not be possible at RHIC using this observable.

Exploring the influence of bulk viscosity of QCD on dilepton tomography

Journal Article Vujanovic, Gojko ; Paquet, Jean-François ; Shen, Chun ; ... - Physical Review C

The collective behavior of hadrons and of electromagnetic radiation in heavy-ion collisions has been widely used to study the properties of the quark-gluon plasma (QGP). Indeed this collectivity, as measured by anisotropic flow coefficients, can be used to constrain the transport properties of QGP. The goal of this contribution is to investigate the influence of the specific bulk viscosity (ζ/s) on dilepton production, both at Relativistic Heavy-Ion Collider and Large Hadron Collider energies. We explore the sensitivity of dileptons to dynamical features that bulk viscosity induces on the evolution of a strongly interacting medium, and highlight what makes them amore »« less

Effects of bulk viscosity and hadronic rescattering in heavy ion collisions at energies available at the BNL Relativistic Heavy Ion Collider and at the CERN Large Hadron Collider

Journal Article Ryu, Sangwook ; Paquet, Jean-Francois ; Shen, Chun ; ... - Physical Review C

Here, we describe ultrarelativistic heavy ion collisions at the BNL Relativistic Heavy Ion Collider and the CERN Large Hadron Collider with a hybrid model using the IP-Glasma model for the earliest stage and viscous hydrodynamics and microscopic transport for the later stages of the collision. We demonstrate that within this framework the bulk viscosity of the plasma plays an important role in describing the experimentally observed radial flow and azimuthal anisotropy simultaneously. Finally, we further investigate the dependence of observables on the temperature below which we employ the microscopic transport description.
