Dilepton emission in high-energy heavy-ion collisions with viscous hydrodynamics

Understand

The invariant mass spectrum and the elliptic flow of lepton pairs produced in relativistic heavy-ion collisions at RHIC are studied with viscous hydrodynamics.

• The effects of viscous corrections on dilepton observables are explored.
• The lepton pairs originating from charm quarks evolving in the viscous background are seen to be a good probe of quark energy loss and gain, as quantified by the dilepton spectrum and by the dilepton elliptic flow.
